Earthing is done to make the unwanted charges flow down to earth through a conducting wire. Earthing is the proper connection of exposed metal parts of an electrical circuit to the ground. It is accomplished by thick copper wires. Earthing protects the appliances and human beings in case of insulation fail or accidental short circuit. When the live wire touches the earth wire, large current flows through it and causes the fuse to blow off or circuit breaker to trip and thereby protecting the appliance as well as users.

Earthing is usually done to prevent extensive damage to our body as well as domestic appliances.
When high voltage comes through electric wires, then our appliances can be damaged. Also, during lightining in the sky, a metal rod is connected to heavy metal plate beneath the building or house. This is also called 'earthing '.
