The time it takes to die by electrocution really depends on the amps. Found this online and thought it was interesting.
the volts is not what will kill you. It is the current transfered, ie the amount of electricity transfered. Lethal current is about 20 milliamperes. So you could have a million volts, but only say a 0.00001 milliamperes and it wouldn't kill you. On the other hand you might have 20v at 1 ampere which would kill you.
nah. 20v at 1A wont. seen a guy touch a truck battery on both terminals once. and truck baterries are rated 24 volts 12-20amps... nothing happened.
