What is Earthing? Explain different methods of equipment earthing.

Earthing is the process of connecting the non-current carrying parts of an electrical installation or equipment to the ground, ensuring that in case of a fault (such as a short circuit or leakage), the electrical current flows safely to the earth. This helps to prevent electric shocks and ensures the safety of both people and equipment.

There are several methods of equipment earthing:

1. Plate Earthing: In this method, a copper or galvanized iron plate is buried in the ground at a certain depth. The metal plate is connected to the equipment with a copper wire. ______ ___ ____ ______ ___ _____.
