    100 volts at 500A:eek: . i thought that would have killed you instantly and probably would have fryed you:confused:

    No, his hands were dry so were a high resistance.
    Use Ohm's Law:
    His hands might have been 100k ohms. 100V across 100k is a current of only 1mA.
    The power in 100k ohms with 100V is only 0.1W which isn't enough to fry anything.

    For a very high current of 500A to flow, the resistance must be only 0.2 ohms.
    The power in a resistance of 0.2 ohms with 100V across it is 50,000W.

    Even if the leads penetrated the skin I don't think you could get .2 ohms, unless the leads were very close. In which case the water in the skin would vaporize and you'd explode a small patch of skin. Lovely thought.
