Question

name two wire having same potential difference write use of earth wire in house hold circuit​

Answer 1

Heya broski!

Here's your answer

The live wire and the neutral wire in India have a potential difference of 220V.

The wire with a green insulation cover is called the earth wire which is attached to metal plate buried deep in the earth for safety purpose especially in appliances with a metal body like refrigerators, metal toasters etc., where the metal body is connected to the earth wire because it provides a low resistance conducting path along which current can flow without leakage into the metal body and keeps it potential to that of earth itself. This prevents the user from getting a severe shock.

Hope it helps And Have a great day!

Thank you! ❤️
