When do we say that electric appliances are earthed and what is their function and why is it necessary to eath electric appliances having metallic body?
Asked by RameshChandraPanda | 22 Sep, 2013, 08:36: PM
Expert Answer
Electrical appliance is earthed when its metal body is connected by means of a metal wire to the earth. This is done so that any leakage of electric current is transferred to the ground and the risk of electric shock is avoided.
