Answered by franktheruler

The potential difference between positive and negative wires in India is 220 V.

Volt is the SI unit of potential difference . It can be obtained from the formula V =IR. The resistance acts as a deterrent to the current flowing through the circuit.

The potential difference is different for different countries according to the energy needs and power supplying capacity.

The potential difference is the actual energy which makes current flowing through the circuit. No potential difference means no current.
