How much DC or AC Current that a Human Body withstand for
Electrical Shocks?

Answer Posted / hussain

current greater than 15 mA can cause death. this why hand
held tools are 42 V or 110V ac with centre tap ( means 55
V ) and human resistance at 50V is 4000 ohms and that
produces 12.5 mA ( less than 15 ma).
Most ideal to use is 42 V where human reistance is 4200
ohms resulting in 10 mA the safest.
