Answer / hm

earthing pin is longer bcoz when we put into the socket, 1st
it gets contact with the earthing point so discharges the
charges remaining previously on the equipment if any, and
neutralizes the surface of equipment 1st. then the other two
pins get contact with phase and neutral of socket.

Answer / kaustuv

another reason is that....even by mistake we can't insert d
earth pin into live socket....If for instance the earth pin
comes in contact with the live wire....the metallic or
earthed part of the device is in direct contact with live
wire and we will get an electric shock if we touch the
metal body of the device.
