Answer 1

Induced low voltage on metal equipment which causes low shock can be prevented using earthing.
The main function of the earth wire is to prevent the live wire from overloading and absorbs the excess electrons & flows to the ground.
Earthing is necessary to give protection against the danger of electric shock.
The earthing protects the apparatus and personnel from the high voltage surges and lightning discharge.
The earthing provides the easiest path to the flow of short circuit current even after the failure of the insulation.
The earthing protects the personnel from the short circuit current hence it provides safety against shock.
