7 - 12 A Biology of Electrocution . Considering that sources report that.07 ampere can be fatal, when sources reporting the current in an electric chair varying by 1 or more amperes, this amount is a large difference. My sources range from 6-20 amperes. It's difficult to explain why there is such a difference. Perhaps each state has it's own electrocution voltage and current regulations, perhaps each human is unique and each person needs a different amount of current to kill them.
Electrocution often requires a few shocks of a lengthy amount of seconds to execute someone.
The strangest result I found was the current being 700 volts. This is definitely a typo on the web-site, however, when posting numbers for the public to view they should be checked. Confusing voltage for current is a major error especially from an electric chair home page. They should correct the voltage. Overall, a current of 5 amperes or more has been described to singe flesh, hair, and eyes.
