## 10A electric shock

I got hit today with 10Ampers and 220V electricity. While i was holding a metal desk with one hand I touched the power line of 10A 220V with other. The force went in from my hand through my heart and chest and went out from other hand.
I read that even 0.2A is lethal, so why didnt it strike me down?
I felt a bit bad and nauseous. I then called an ambulance and they took me to hospital where they kept me for 3-4 hours, and let home after checking all the data, which came out clear.
For now its been about 8 hours and i still feel a bit bad and little pain in chest, but nothing else. Should i be worried at all anymore?

I'm thinking back to university physics here, and it's been a while. But:

Voltage = Current (amps) * Resistance

So if that circuit is 220V, then the resistance in the wire to generate 10 amps is (220 / 10) = 22 Ohms

The average person is 100,000 ohms dry (if I remember right) and 1,000 ohms wet.

So dry you would have gotten (220 / 100,000) = 0.0022 Amps (which is similar to what you described)

If wet you would have gotten 2.2 amps, and you'd be very dead.

Touching the desk just gives a path for the electricity once it leaves you, it doesn't change your resistance.

That being said, I could be completely wrong (someone let me know please), this is just what I remember.

because the physics in place allowed it to be.

Without knowing absolutely everything about the situation, it is impossible to determine why you got shocked or how much current actually flowed.

anyway, there is documentation showing that a person that is shocked can die hours after the shock due to cardiac or respiratory arrest. If you are feeling bad, I would suggest not being alone until at least tomorrow.

You should drink to replenish the electrolytes in your system. Gatorade would be good, or at least water.

chances are you were only hit with 120 volts. In a US residential situation, each line of a 220 volt circuit carries 120 volts. You would have had to make a line to line connection to be subjected to 220 (actually 240) volts.

also, can be doesn't mean it always will be. Think about people hit with lightning: some survive, some don't.

That sounds like a pretty severe shock to me. Also 0.1 amps is lethal, less than that is still often lethal, as in Tasers which have killed people with as little as 0.01 amps (which is only 5X more than you likely got). What I can say is there is no way you got 10 amps, you are not as conductive as copper wire. When you put your finger over a 9V battery you don't really feel anything. Put your tongue over it and you feel a lot more, due to the difference in resistance between your finger and your very wet tongue.

Ok, so you probably got hit with whatever your single line voltage is (I can never remember the foreign systems)

. It's what, already at least 1 am where you are? How long ago did this happen?

 06-02-2010, 05:20 PM #8 Newbie   Join Date: Jun 2010 Posts: 13 Rewards Points: 10 this happened about 12 hours ago, and it is 0.20am I'm feeling weird @ my left chest, about where the heart is, but it isnt painful. And a bit shaky.

Drag yourself back to the hospital. Might as well spend the night there to be on the safe side. Good luck __________________ If I could only remember to THINK about what I was doing before I did it.

If most peoples' skin/body resistance most of the time is between 300 and 3000 ohms you got hit with 0.7A to 0.07A.

An elec. chair is 4A to 8A at 2400 vac. so the executionee is presenting 300 to 600 ohms.

I think there is a decimal point problem here, but you could have had momentarily something in the 0.1 to 0.2 amp range flowing through your body. Trog is right,the current flow though your body was not near 10 amps.

Supposedly the able-to-let-go current is <18 mA.

(220v^2)/300 ohms for one second is 160 joules, about equal in energy to two 0.45 slugs. More than 1 joule can be fatal and those defibrillator machines can put out 200 joules.

You would have been 1 of 1300 people in the US [out of 300M] who get electrocuted each year. The odds are with you.
