Answer:

In electrical circuit generally in wiring there are two type of wire in a two port network .

1. Live wire (carry electric current )
2. Earthing (earth wire )

• What is earth wire ?

Wire which is used in electrical circuit to produce large potential difference between two ends of wire so that current easily flow through wire in two ends that wire is called earth wire .

• Why earth wire is used in a circuit to produced potential why not other .

Earth have large potential difference due to it's large shape and size so it is used .

Answer 2

In electrical engineering, ground or earth is the reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the earth. Electrical circuits may be connected to ground for several reasons.

ahh love you give me all ur points hahaha
