Answer:
Earthing is used to protect you from an electric shock. It does this by providing a path (a protective conductor) for a fault current to flow to earth. It also causes the protective device (either a circuit-breaker or fuse) to switch off the electric current to the circuit that has the fault.

Earthing is provided in the building to protect us from electrical shocks due to any leakage of electrical current. It is done to provide safety by minimizing the shock, if someone accidentally touches the faulty wire.
