What is meant by saying that the potential difference between two points is 1 V?
Potential difference is defined as the work done to move per unit charge between the two ends of the current carrying conductor. Potential difference is designated by V.
V=W/Q
If 1 J of work is required to move a charge of amount 1 C from one point to another, then it is said that the potential difference between the two points is 1 V.
