Potential difference between two conductors is equal to the work done in transferring a unit positive charge from one conductor to the other through the metallic wire.

If W is the joule of work done in transferring q coulomb of positive charge from one conductor to the other, then the potential difference V between the two conductors is given as

It is a scalar quantity. Its SI unit is volt (V).
The potential difference between two points is said to be 1 volt if the work done in transferring 1 coulomb of charge from one point to the other is 1 joule.
