In the circuit, these three wires look like
Live Wire |
Neutral Wire |
Earth Wire |
Live wire is connected directly to the generators of the power station |
Neutral wire returns the electricity to the generators by completing the circuit |
Earth wire doesn't carry electricity, it is used to prevent people from getting electric shocks |
Voltage of Live Wire is same as that main supply (in India 220V) | Voltage of neutral wire is approximately 0 V | Since Earth Wire is not connected to electricity, its voltage is 0 |
