ok here it goes....i thought about sharing this story about what i done during a boring physics lesson at school, it sounds quite dangerous, but luckily i am still alive to tell your guyz out there.
I was bored during class when the teacher was explaining facts about an electric socket. The teacher told us many facts about an electrical socket that gives an output of 240 volts and 0.5 amps. And then he said that 0.1 amp can kill someone. Without realizing or caring about what he said, i was dared by my friends to shove a pair of scissors into the socket and turn it on. Once i did it, the whole classroom lights suddenly blew out, and all electrical appliances that run on mains switched off. Sparks then came out of the socket holes and I was laughing.
Luckilly the teacher didnt see me or anyone else appart from my friends. After the physics lesson, everyone said that the whole of the 4th floor had a blackout. And dats the point where i laughed hard
I still dont know why i did that in the first place, although i know it was a stupid thing to do and i could have got myself killed. But all i really know is that i blew up many fuse,
it's described at walking on the edge of committing a darvin
Well, I'm not sure if your teacher is mistaken or you've just remembered it wrongly, but a 0.5A on a 240V is not sufficient to power many things. E.g., the total power of a 240V 0.5A is 120W, that's slightly higher than an old fashion 100W lightbulb. The max plug in UK (which I believe is so in HK) is 13A, that is more than 3000W, which then can be used to power stuff like an iron/heater, which goes around 2000W.
Pluging in the scissors to the socket short circuit it and hence creating a flux high current, blowing/triggering any safety fuse along the way. Since you said the entire floor was blackout, it seems that it only blown/triggered 1 major fuse. Unlikely it will cause multiple blown/triggered fuses.
On the 0.1A killing a person issue, if you consider a person's resistance is 2MOhm (which I think is higher than that), it would take a relatively large 20MV (that is 2x10^7) voltage across, which you can't easily get (if not impossible, consider a high tension cable is probably around 1MV). If you were to get that kind of voltage, the power across would be 0.1x0.1x2MOhm = 20,000W, which would definitely kill someone. Consider the amount shown, I bet it takes less than 0.1A to kill someone. To put into perspective, a Taser gun has a peak (not constant) voltage of 50,000V, which is (consider the 2MOhm assumption) 0.025A.
FYI, in most cases of electric shock cases, the fatal part is usually the duration of the electric shock (i.e. small continuous current flowing, cooking you for 30 minutes) or hurting yourself after a shock (i.e. knock yourself onto the solid ground after a shock).
Anyone fall asleep yet? anyway, whatever you do, don't mess with electricity. Respect it.
p/s: Sorry for the lengthy lecture above.. "occupation sickness".

You might want to lay off the pipe. As you can see, there is no good that can come from it.
16 Volts AC straight through the heart can be fatal.
AC requires about 60 mA to cause fibrillation, DC needs 500 mA for the same result. Fibrillation is not always fatal....

Anyone here watching "Myth busters"?
They did a whole episode on throwing electric appliances in to bathtub and measuring the current across the "heart" of a dummy to see if dropping a hairdryer or toaster in the bath can really kill you.
I didn't see that Mythbuster. I guess it should be confirmed? Although there are lost of circumstances influencing the outcome:
-use pure H2O, it hardly conducts
-use non-ionic bath oil (good for the skin too)
-a decent Residual-current device would cut off power before you can even notice it
-a decent low amp fast fuse could be a life saver
-high ionic bath salt makes the water much more conductive than your body
-place the tub on rubber, use PVC water supply and drain pipes

oh, right, a gel doll again... very nice material for ballistics, although I believe they should put bones in it for realistic results.
Arteries, veins and nerves are full of ions giving excellent conductive paths through our body, I doubt if they simulated those in the gel.
I got kicked out of woodwork when i was 13 for tying a pupils tie round a lathe and threatening to turn it on, because he had made a better baseball bat than me, unfortunatly, for him, my friend hit the power button and nearly killed him, we promptly got suspended and moved into sewing as a punishment, with a teacher from hell. My friend who i wont name decided to wire up some gold thread to the mains socket and complained to her(teacher) that the machine was faulty, needless to say when she touched the machine she was electrocuted along with my friend, who was promptly expelled, and i was giving a severe caning, in those days we had no trip switches so the only thing that saved them both was the thin gold thread that blew as well.
Moral of the story is dont mess with electrics, or hang around with nutcases

With an heavy insulation on the outer body part (i.e. skin = not very good conductor), not even a gold wire inside the body matters. Further, I suspect that the water and the bathtub plays an important part as well.
First, consider that you throwing an electrical appliance into the water, chances are, the 'Neutral' line will be in the water (together with the dangerous 'Live'). Any current from the live line will eventually find the shortest path to the neutral line, leaving the rest (i.e. probably you) untouched.
Then, consider that the current is increased, hence requiring not only the shortest path to the neutral, but a lot of paths to the neutral as well. As with the Faraday cage theory, electric current will tend to go around an object (i.e. electrons repelling each other), especially a better conducting one (i.e. a car protecting the driver from a lighting strike). As such, in terms of choice, if the current require additional path to go to the neutral, chances are, it will rather go via the water (better conductor, I think) or the steel bath tub (i.e. like the body of a car), than your body.
Hanmin, your whole story sounds fair enough... for laymen.
First of all you're mixing up AC, DC and static behaviour.
Faraday created spectacular shows using extremely high static charges, indeed comparable to a car hit by lightning. If you want to conduct an experiment with a metal bath tub filled with nice warm water and any bath soap, salt or oil struck from the side by lightning, I volunteer to step in.
So, our PC's have metal housing, you'd say, so they're a Faraday cage? Right? Wrong. I've had a computer company near the Dutch coast where thunder and lightning are regular events. I could tell when repairs would come in the next day. Phone, Lan and power wires go straight into the metal cage without making contact with the cage itself. Lightning doesn't even have to strike these wires directly, induction can be fatal for your equipment.
Edison called AC "the killer current" and refused to sell AC. AC can not "flow away" to neutral, it wants to go to earth/ground. As long as the fuse doesn't blow, it delivers as much energy as it can. In a bath tub it will not behave like lightning trying to find the shortest way, but like a cloud, spearding as fast as it can. Remember electrons all have the same negative load so they push each other away. And they are LIGHTning fast.
That's why it's also not a good idea to use a standard vacuum cleaner to clean your PC on the inside: the motor will create a cloud of electrons trying to find a way to ground. The free electrons can move much faster through the cloud of static charged dust particles toward your PCB than the slow air stream moves to the vacuum.
The surface of the dry skin is indeed a bad conductor. But even good enough for ECG using leads with suction cups or stickers. And ECG measures very faint electrical pulses in the heart, even with leads on the hands or feet.
Most people believe that water is a good conductor. But in fact pure water is an almost perfect isolator. And even tap water in most Western societies is so pure that you can hardly split it into hydrogen and oxigen using a fairly safe 12 V DC set up, not without first adding a hand full of salt. Current needs ions to move through a liquid, our bodies are full of ions, tap water has much less.
Niiccceee.. good that my explaination has someone to read it in details. I'm so worried that my stuff will get everyone to sleep. Anyway...
You are right that the induction from a lighting can toast your phone, lan and power line. However, as these lines are not long and straight enough anywhere near the PC, the fatal induction is actually caused by somewhere along the way to your company (e.g. from the phone exchange, along the telephone pole/underground, to your company). Your PC will be safe from lightling if it is disconnection from possible external induction source (e.g. the phone line to the outside world). I'm happy to put myself inside the PC case (if it is big enough) for a lighting strike
Some history lesson for all. Edison called the AC the killer current mainly because of the business competition between the DC and AC business. As Edison has spent a lot of money and effort just to change the public point of view on the safety of electricity, and just as the business is getting some money... this Tesla (I think) guy made AC electricity and business is good (costrofit ratio), due to the fact that AC has a certain edge on long distance transfer (I'll omit the details on this). Hence, Edison is trying very very hard to make AC look dangerous, by killing innocent animals (in some cases, virtually just cook it), and eventually, co-invented the electric chair.
In the view of the danger of DC current, it is a false impression of most people thinking that DC current is safe, mainly because the DC current we normally exposed to are low voltage DC current (e.g. batteries and phone charger). However, in strict AC/DC defination, a lighting strike is a DC current. And, I think a Taser gun uses DC too (you would certainly need to use some form of capasitor to store enough voltage for a shock, using regular batteries), unless the battery use is exceptionally designed for it.
Anyone has a Taser to confirm this? Does it gives out a buzzing sound from low to high frequency when armed some AA batteries operated cameras with powerful flash will have the same buzzing noise, indicating that the capacitor is charging, ready for the flash).
As for your statement of "AC can not 'flow away' to neutral, it wants to go to
earth/ground.", I'm not sure if you really meant "can not", or "not only". Anyway, all AC electric stuff, electrons goes between live/neutral, and does not require the earth/ground to be functional (not safely, at least).
If you remember some electric circuit theory, if caes where you have two parallel line (AC or DC), with one line much lower resistance (i.e. shorter distance between live and neutral) compared to the other (longer distance to 'ground' where 'ground' is not designed to pair with live), majority of the current will go through the lower resistance route and hence current that goes through the high resistance route maybe very well harmless. HOWEVER, there are cases where the current in through the high resistance route is harmful, that are in the cases where the current going through the low resistance route is excessive high. Example, the low:high resistance current ratio may be 100:1. If it takes (say) 1A to be fatal, the other route will need to have 100A (which will have all fuses nuked - e.g. my house has a main fuse of about 80A for both the heater and the cooker). That's what mentioned on my post above around the "consider that the current is increased..." section. And, as for the case with extreme high current, apply the Faraday thing mentioned on your first paragraph.
Take the Taser gun for example. If you were read the user manual, there is a minimal distance requirement between you and the target, due the the fact that the probes triangular trajectory path. Being too close to the target, will cause the probes to be too closely attached, not giving enough muscle area to 'disable' the target. The electron will not spread around (like clouds) through all the muscle, just the shortest route to the other probe (there may be current through other muscles, but too small to be noticeable).
Where in the Western societies are you in now? US? Nice... in the UK, you are/not so lucky, as you dont get very much pure water over the tap. UK is on hardwater, which seemingly adding mineral to the diet, probably in such situation, protect us from electrocution? If you were to be 1+ hours around London, take a bit of tap water, leave it on any surface and leave it for it to evaporate. At the end of the day, you'll get a pile of white powder. Yes, it is this bad.
As for the ECG issue, it goes the same with the low-vs-high resistance route. I'm sure it wont work underwater (dirty water?). However, still, it is a better conductor than many things.
Taser guns use electronics related to those modern tiny switched power adapters. The result in both cases is indeed DC. The physics of the lightning path are very complex, lightning can fork out to lots of places being hit by one strike but in general you're right that DC/static tries to find a short route.
In one of my first messages in this thread I mentioned what DC it takes to kill, so yes, I'm well aware that there is no such thing as "safe electricity".
If you short a capacitor or battery, current flows in one direction, from high potential to low potential till both potentials are equal.
AC doesn't come in batteries or capacitors, it comes from a generator constantly pulling the potential from above neutral to below neutral, 50 or 60 times a second. If you would short circuit the generator itself it would continue to produce electricity as long as it hasn't killed itself. There is no flowing away till both potentials are equal.
I'm a retired computer engineer, but I still do remember Ohm's law, thank you.
In case of the bath tub it means:
we have a fixed voltage (U) of 110 or 220V, depends where you live
we can measure resistance (I) from the device that drops into the water to the feet of the tub, to the tap, to the drain
U=I.R in this case U=I1.R1+I2.R2...InRn
With an 80A fuse, the radio falling on the feet, the tap behind the back and the drain and two tub feet straight under it it seems likely that about 2/3 of 80A, well lets say 50A will strike you, 50 x 110 = 5500W
That should boil the egg if not electrocute it
I WOULD SAY YOU WOULD GET A GREAT SHOCK FROM A TOASTER IN A BATH. If you took a mains plug and put two springs on the live and neutral and inserted this into a bath of water it would generate heat, i know i have boiled a cup of water for tea by this method. so if the electricity didnt kill you you will be boiled like an egg
yeah in some situations i see myth busters as more intertainment then real science
like when they had a rather small boat as an example of titanic pulling people down when it went down
a such a small raft cant compare to titanic in ways of down pull
but they are ok fun
but if they bust a myth dont mean a 100% bust in my book

Equations, I like! For the case you've calculated above, you consider that the full 80A is flowing. And weirdly, you seemingly considering that 2/3 flowing through a human body. Lets look at this, at the 50A you mentioned (yes, you are right, 5500W will cook you very well). Consider the worst case of U at 240V, your body will have to have (U/I = R) a resistance of 4.8Ohm, which is weirdly small, dont you think?
As with scousemartin's boil an egg, you will have to consider the large amount of water in the bath tub as oppose to the amount of water you use in boiling the egg (e.g. it would take really long for the water to boil) And, even IF the water has similar rate in raise of temperature, I'm sure the person involved will be pretty quick to jump out of the water (when a toaster hit the tub) before it gets boiling.
Just recently moved to Chicago. I work out side quite a bit, and will be in the winter. Normally I keep my phone in my inside jacket pocket when I lived in Atlanta, No where near as cold there. Was just wondering what do you all recommend? Keep phone inside somewhere or do you think between my body warmth and the jacket, it would be fine. Not sure temp would start to damage the phone. I know when I came up here for New Years my old tour(9630) in just my pants pocket started to freak out.
Thanks for your time.
Sent from my SPH-D700 using XDA App
what u need is a hiking backpack, a generator, and a toaster to put ur phone in
Phone temp. doesn't affect much depending on how low of temperatures we are talking. anything lower than 0C (30F) I would get worried about. At lower temperatures issues with battery and LCD's happen. So I think as long as you keep it in your jacket close to your body heat it should be fine.
Yeah, in your inside pocket just body warmth will keep it safe. The only things I have noticed with cold phones is batteries discharge faster and lcds will stop responding. I have had a few phones freeze inside my truck when I leave them inside when I was hunting, but besides probably killing the batteries faster than usual I have not had any serious problems. Just warm them up before you turn them back on!
Lol @ hiking and toaster. As far as how low for temps I wouldn't think anything below 0 but then again this will bemy first winter up here working. Its not like I plan on being in the cold long. But you never know. Thanks for the quick replies. =)

I used my g1 in temps ranging from 110 to -10 (farenheit) with only minor issues. At warmer temps the battery seemed to discharge faster and below 20 the screen wasn't very responsive. As stated above, just keep it in an inner pocket when cold.
Welcome to Chi town. Enjoy your stay and the crappy politics. 30 degrees or below for more than an hour it goes in the inside pocket or I will stash it somewhere inside a building till I am done working outside.
good day.
Cold temperature couldn't cause serious damage to phone, only that it could sluggish, or make a fully charged one turns to low battery. You might encounter some screen problems but nothing a warm room couldn't fix. Definitely, your cellphone can surely survive a day on the slopes without worry.
I'm going to put short sentences for quickness
Bought N6 off Mobile Phones Direct. Good service. No issues.
Phone charger starts whittling.
Motorola replace charger.
Phone slowly develops symptoms of dodgy battery within 6 weeks:
Expanding battery, case pulling away, red hot charging and draining fast.
After lots of liaison with Motorola who did their best to suggest it was my apo usage they eventually take it for repair. I sent it off ' immaculate ' apart from the fault.
Despite me sending loads of documented online proof that devices like this are being replaced, the Phone comes back 'repaired' not replaced which disappointed me.
Any way I get it back a week later, and initially the phone seems better; apparently it's had a new back and battery.
However I noticed the back was not flush. About .5mm out in alignment and its slightly raised.
In addition, the phone battery gets up to 40 odd degrees when charging and at times it's not pleasant to touch, it's that hot when charging. This is how it all started in the first place!
They've offfered to take it back 'again' and do a ' sort this once and for all ' repair.
I just feel hard done by here. The phone was brand spankers in April and 3 months down the line it's in for a second repair and Motorola aren't even considering replacing this obviously dodgy handset.
If this second repair isn't perfect and working satisfactorily, surely I have some sort of legal rights here to demand a replacement under the not fit for purpose sales of goods act ?

40C, you do realize that a human body on average is at 37C?? 40C isnt even close to being considered hot. when charging, 40C can be considered cool, not hot. lol.
Yeh I realise this I'm just saying that the CPU temp app suggests that temp, but to touch the phone is red hot. Like a cup of tea after its been sat for 10 mins Max.
Thanks for the condescending tone though.
Red Hot suggests burning your skin off. Red Hot would melt the device.
The device is going to get somewhat hot. Not red hot as you suggest.
If that were the case, you would easily be able to separate the glass from the LCD and also pull the LCD from the frame.

unfortunately, feel isnt an accurate way to discuss temperature. all feel does is show you whats warmer or cooler than what you are feeling with. and that has nothing to do with my tone towards your issie, it just is what it is. i read people complaining constantly that their phone reaches 40C(lol). well, guess what, it can get much hotter normally, up to 100C, thats 212F, or the boiling point of water.
i feel bad for you about your issue, but that happens. but 40C when charging has nothing to do with it.
I'd send it back for the second look-see, since you feel that the back is out of alignment (picture, please?)
I'd offer that the heat issue doesn't seem extreme for a phone, depending upon how it's being charged (e.g., fast charge). Also, do you keep this in any sort of case, perhaps?
I've actually never used the Motorola charger, instead I use a USB 99% of the time. I do recall reading about battery issues with a minority of folks who used the fast charger, so perhaps that's what you initially hit?
- ooofest
For starters the app might be inaccurate but all I know is the phone to touch is considerably hot. Heat kills battery life or increases degradation so therefore it won't be long at this rate, before I need another new battery. My point is this is how it all started and its starting again. Motorola seem quite happy to keep repairing. My simple question was where you feel I stand before claiming unfit for purpose. In a 2 year contract I expect the phone to be reliable but i have no trust in this device. I'll send it back see what they do. Probably another case and send it back.

and unfortunately, touch does not give you a temperature reading. ok, try this experiment, itll show you about touch and temperature. get 3 glasses of water, one cold, one hot, and one room temperature. put your left hand in tbe cold water and your right hnd in the hot water. keep them there for about 3 minutes. then take out both hands and put both hands into the room temp water. your left hand, which was in cold water, will now feel warm. and your right hand, which was in hot water, will now feel cool. yet they both are in the same temp water.
anyways, send it back, and a hope for a better future from me to you
Right.....Thanks for that. However I know the difference from a phone thats warm to touch and overheating. I expect warm, but I know the phone should be getting this hot, end of. I'm not the only one as well with this issue... Just do a google search. See for yourself. Clearly im pissin in the wind here.

Mobile Phone Direct in the end replaced - as I was told it fell to the retailer regardless of 28 days or not, if its within 6 months in the UK it falls to the retailer in cases like mine with faulty products. In the end, after sending the phone off to the retailer, they replaced it with a new one one, no issues - took long to get there, but I did in the end.
The new one was perfect throughout my contract. Not a single overheating issue - although it did get warm when charging (nothing like before) and the battery and back cover remain fine.

The brutal cold of winter isn't just capable of breaking your spirits – it can break your phone, too.
According to Apple, iPhones and iPads should be used in temperatures between 32 and 95 degrees. As cold temperatures persist and we spend time outdoors, taking smartphones or tablets with us could negatively impact the performance of those devices or cause them to shut down altogether, Apple also said.
There are other side effects on your smartphones that could be caused by cold temperatures, Huffington Post reports. If you notice the device isn't responding to your touch, or the battery drains rapidly, those are signs that the frigid air is getting the best of your phone or tablet, the report added. Once this happens, it's time to get your device to a warm spot to give it a chance to recover, Apple recommends.
For android and all devices
Cold weather means screens and internal components can become more brittle and fragile, so dropping a phone or tablet could be even more dangerous in the winter than other times of year. Make sure you have a protective case on your device, and don’t take it off, especially outside in the cold.
If you’re in a temperate region, it may seem incredible, but smartphones actually stop working around -40°F, and some at even warmer temperatures. Even moderately cold winter temperatures can make your phone or device seem sluggish. Don’t be alarmed, but try not to use your device in very cold temperatures.
Keep your device in a pocket close to your body if possible when you’re outside for a while, and protect it from snow or other precipitation. If you need to take a call outside, use your earpiece or headphone controller to answer and keep the phone sheltered and warm in your pocket.
Don’t leave devices overnight (or for long periods) in a car in cold weather. Exposure to very cold temperatures can permanently damage components.
If your device has gotten cold outside, let your phone warm up to room temperature before using; otherwise you risk condensation forming inside the device if it heats up quickly after coming inside from the cold.
Take good care of your device and you can avoid electronic frostbite this winter!

If your device has gotten cold outside, let your phone warm up to room temperature before using; otherwise you risk condensation forming inside the device if it heats up quickly after coming inside from the cold.
Take good care of your device and you can avoid electronic frostbite this winter!

Yes Mi phones can generate heat which can prevent you with cold... so I recommend you to buy a Mi phone if you are in a cold region but if you are in the Heat region dont go for Mi phones then there is more chance of you dying soon.
