Problem
An electric iron has its metal casing connected to earth through a wire of resistance 1.5Ω. Due to insulation failure, a leakage current of 40mA flows to the casing.
Calculate the potential of the casing with respect to the ground and state whether this potential is high enough to cause a dangerous electric shock (take the danger level to be about 50V).
