Zero? An electric arc (aka "spark") in case of thunder doesn't come from a wire, do you know where it comes? Do you realize how big they are to store that kind of energy?
The point I was making, you missed entirely. You said the wires were too thin to injure even an infant - obviously lightening has a lot more energy - BUT - it has no wire whatsoever - and can still kill people. Your thinking the wires in a USB cable or the transformer being too thin to cause bodily harm or death is WRONG - flat out WRONG. And shows how little you truly know. That charger (assuming it's USB2 standard - as we don't know exactly what model it is) puts out 0.5 AMPS. As little as 0.1 AMPS will kill someone. Here's one source: http://en.wikipedia.org/wiki/Electric_shock How about you show me a source claiming those wires being too thin to cause harm. Because I've never seen that claim by anyone - but you.
I googled, problem? Anything to do not with overheating?
I have no idea what those sentences mean or refer to. Seriously.
A transformer (in case of a SMPS, a 1:1 transformer, usually) is connected to the plug.
A transformer isolates two circuits, the connection between the wall outlet and the PCB is made
magnetically, that's what a transformer does.
Anyway, the copper wires are so tiny in the transformer, it can't pass much current, because it acts as a
fuse.
Once again - you claim it's impossible for this to pass enough current to kill someone, 100ma worth - yet somehow - magically - it IS able to pass 500ma or more - to charge the phone connected to it. Simply, amazing. How is that possible? Please, cite a source or reference backing that claim up.
But that's if you charge a great load of volts and discharge them fast.
Do you not understand the conditions for power transfer? If you have a high voltage potential - you tend to discharge faster, as the dynamic resistance of the load - will be lower. Besides - that's of no consequence - my point was that DC can, and does kill. 500 volts DC is no safer than 500 volts AC. Ohms law applies to both AC and DC equally - so how do you believe one can shock someone, while the other cannot?
A capacitor that size even won't fit inside a iPhone charger.
I never - NOT ONCE - claimed it was a capacitor in this iPhone charger that caused the death here. Again, I was stating how DC voltages can also be dangerous.
Power(W) = tension(V) * current(A)^2
I'm containing myself to don't call you stupid.
I have a better idea - how about you prove it - show me - how I'm wrong. I want to see some sources and math to back it up.
That's nice. Pics or it didn't happen.

There's your pic.

There's a source backing it.
A truck battery can't discharge sufficiently fast to have enough power to kill a man. A truck battery won't make an electrical arc because the voltage it's too low. And it's DC.
Idiotic statement. Can't discharge sufficiently fast? So - 0.100 Amps can cause death (this has been proven) - and truck batteries that are RATED IN CRANKING AMPS - that can be well in to the THOUSANDS OF AMPS - can't discharge sufficiently fast? I didn't say anything about an electrical arc - by the way - they can and DO arc - even with low voltages. Look at this, type "truck battery arcing" into Google - and I get 1.7 million hits.
Thank you caption obvious. Water doesn't do anything unless connects one end to the other end.
So, I stated that I was holding both buss bars - as in - I was connecting one end to the other end. With wet hands, and nothing happened. Your comprehension skills are beyond failure.

Here's a definition: http://en.wikipedia.org/wiki/Buss_bar
Yes, humans aren't perfect conductors, in fact, human skin is a good isolator.
SOMETIMES - again, failure to comprehend that I was pointing out. In some scenarios we're poor conductors - but in others - we're relatively good. That there are no hard or absolute conditions dictating how much electricity we conduct.
