Answer 2

Answer:

Earthing or grounding is the process of transferring the immediate discharge of electricity directly to the earth plate, by means of low resistance electrical cables or wires.

Earthing is an important component of electrical systems because of the following reasons:

1. It keeps people safe by preventing electric shocks.

2. It prevents damage to electrical appliances and devices by preventing excessive current from running through the circuit.
