WebThe answer is very little. A current of as little as 0.007 amps (7mA) across the heart for three seconds is enough to kill. 0.1 amps (100mA) passing through the body will almost certainly be fatal. However, the current involved in an electric shock is determined by the voltage and the resistance of the circuit.
