Threshold level of electric shock perception caused by electrostatic induction generated by 50Hz alternative current has been studied. The results are summarized below. When the surface of an insulator is wet with hydrophilic condition, the surface acts as a conductor under electrostatic induction, and one may perceive electric shock when he/she touches the surface. In conclusion, the minimum threshold perception voltage is about 1000V (r.m.s) when one touches the surface, pinching a copper coin in order to lower the resistance. However, the threshold level of perception is not concerned with the voltage or the amount of the electric discharge but a peak value of the current flowing through a subject, furthermore, the length of electric discharge time is also infuluenced. And a peak value of the current is about 1500mA.
