Live wire is connected directly to the generators of the power station

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
