I got news for you.

When he took the juice, it was 220V, not the 5V chargers put out.

The chargers put out 5V at 500mA. This would never cause the reaction seen in the video.

What happened is that due to terrible engineering, the 220V source somehow made it the the wires meant to carry 5V at 500 mA. The current draw would depend on the conductivity of his body. I doubt it was 500 mA. Quite a bit more is likely.

And this is why electrical engineering is a discipline that requires study and mentorship.

I agree with your assessment. In engineering school, I think we estimated each limb to be 300 - 500 ohm.

V = I * R 500ohm *.5A = 250V Or 440ohm * .5A =220V Anyway somewhere in there. Definitely not 10ohm (5V/.5A)

Its gets tricky if you dont know what limb the voltage grounded out at.

Your insides might be that low, but the skin is relatively high impedance. You have to get enough current through it to cause it to burn/melt/break down for it to dip into the neighborhood of 300- 500 ohms. If you actually measure contact resistance from one hand, across your chest, to the other, it's going to be at least 100k - 200K. With wet fingers, you might be able to get it down to 60-70k.

Most people think a lot of current passes through your body when you touch electrical mains because they're capable of supplying so much and most people don't know Ohm's law or the typical resistance of a human body. Unless it burns through your skin to the gooey insides, you're looking at ~4-5mArms (max) through your body when touching 240V mains. Which is still enough to kill you, of course.

Most power strips and breakers are 10 or 15 amp

Yes, it's the current that kills, but the magnitude of current depends on the voltage received, since the body has a different resistance / impedance than the elements the voltage will typically exist across. 5 V is not nearly enough to produce the necessary current through a human body to be fatal. 220 V could do it.

Because of some jackass electrician short wired an electrical box, I got hit with 240v one time and partially welded the metal cover to the box. I was kneeling on joists up in the ceiling over the men's restroom in a mall. I almost fell through. That shock fucking hurt my left arm for an hour or so. It wasn't any kind of fun. No permanent damage, though.

"When he tried to pull the cord out, he got shocked and cried out. Then he touched it again and his foot hit the steel pipe underneath the desk," his brother explained."

Poor China kid became a conductor to their shit grounded power system with no surge protection.

He got the full wack.

500mA is what proper USB is going to try to limit things to. There are a few ways to signal a computer to allow more, and many chargers let you draw more (and signal the device that it can).

This is going to be a failure in the transformer, so that the low and high voltage sides are connected. At that point, I wouldn't count on any current limiting circuitry doing anything.

Once an initial shock starts, the resistance of the human body drops to around 500 ohms. At that point, Ohm's law will limit you to around 500mA. That's not going to blow the breaker, so that really sucks.

I think it is because of some ridiculous law where you could be held responsible for some injuries of you help someone out, thus being liable for medical expenses. I am talking out of my ass, I vagualy remember reading about it.

You can see it in a lot of countries, especially with the "little men" - uneducated and poor people who believe that "the system" is their enemy. That way if you do not get involved, you may not be blamed for anything and suffer yourself.

Hard to tell what kind of noise anyone made. If you're in the middle of a heated match of Popular Real Time Internet Game, you don't have much time to do anything other than "Hey is everyone else running out? No? Ok."

Besides, what could they do. Their reaction is the smart one. :-)

My company loved to issue the cheapest knock off wall chargers to people. It is kind of scary knowing how close you are to a shitty part failing and feeding you line voltage.

I knew a cheapskate like this. One phone blew up in a leased vehicle and he fired the employee. Another involved getting half of the office sick trying to stretch out leftover catering 4 days after a managers meeting disguised as employee appreciation. He was stealing the chargers from the Bell phones then selling them on Craigslist. Expensed the head office of the company for gift cards no one ever saw. Then was caught stealing cleaning supplies from the overnight cleaners.

I like how the cheap Chinese stuff disassembles on its own and falls apart for no obvious reasons. Especially funny when it is an electrical stuff. One charger I had broke in half when I tried to pull it out of the wall. The insides looked like something picked up at a dumpster and stuck together with a chewing gum. I was lucky it did not catch fire.

Sort of true to an extent. There are so many of them, one individual is less important to the whole scheme of things. This is what democrats want in our country. Votes, so people depend upon them for guidance and livelihood.

I know enough not to touch someone who just got electrocuted unless I know why they got electrocuted and can confirm that that danger is out of the picture.

I don't know enough to risk the voltage being so high that a broom handle or something wouldn't save me... unless he were family.

I work with electricity everyday so I know too, but how can you be so nonchalant about that? I've had quite a bit of safety training though in this so maybe it's just me.

Did he really die? he was still moving. Anyway, at 5v for a USB connection, you should be able to lick that cord and you wouldnt get more than a few mA through your body

That's the point... it wasn't 5 volts because of crappy phone charger was involved.

Also... your heart stopping, you'll still have enough oxygen in your brain for a bit to be conscious... and your muscles can still do their own thing for a bit after that too.

Chinese line voltage is typically 220v. All that was needed was a shitty Chinese charger to short out and suddenly your holding a portable electric chair.

[–] Joklyoat 0 points 1 points (+1|-0) ago 

It's not like 220 V is guaranteed to kill you. I have been zapped by 220 V few times in my life, and while it certainly was not pleasing, it did not do me much harm.

Depends upon the conditions probably, like, touching a naked 220 V wire while standing barefoot in a flooded basement probably is not Ok.
