ABSTRACT:
An AC plug provided with a plug casing and prongs formed sticking out from the inside of the plug casing to the outside and supplying AC power supplied from a power outlet to the prongs by an AC cord connected to the prongs inside the plug when the prongs are inserted into the power outlet, further provided with, inside the plug casing in series between the prongs, a discharge resistor for discharging a residual charge across the prongs when the prongs are pulled out from the power outlet and a switch turning off when the prongs are inserted into the power outlet, turning on when they are pulled out from the power outlet to pass the residual charge of one prong of the prongs to the other prong through the discharge resistor.
