Detailed Solution

In a domestic electric circuit, mention the potential difference maintained between a live wire and a neutral wire is 220 V.
The three types of wire used for household circuits are live, neutral, and earth wire.
Live wire: The wire used for carrying current in the circuit.
Neutral wire: The neutral wire is the wire which helps in completing the circuit. The 'return' wire connects the appliance to the terminal of the electric supply source, which is earthed.
Earth Wire: this wire passes the excess or leaking current from the electrical appliances to the ground.
In a domestic electric circuit, the potential difference between a live and a neutral wire is 220 V. 220 V power is very efficient in terms of current because it needs less current to provide the same power due to the increased voltage.
