Earthing is process by which wiring is done in such a way that in case of a short circuit or circuit overload excess current can pass into ground by means of earth wire.
Explanation:
- It’s a part of electricity safety measure.
- Earthing is done so that fire doesn’t break out in case of slightest short circuits.
- Earth is always neutral. So, in case of any potential difference that is caused by earth, current flows from Earth to earth.
