Answer:
The earth wire connects the metallic part of an electrical appliance with the earth. This becomes necessary because if in a faulty appliance, live wire comes in connection to the metallic part of the body and if we happen to touch the appliance, the current and may not flow through our body. Thus an electric wire prevent us from electric shocks.
