What is meant by saying that the potential difference between two points is `1 V` ?

Text Solution

Verified by Experts

Potential difference between two points in a current-carrying conductor is said to be `1` volt if `1` joule of work is done to carry a charge of `1` coulomb from one point to the other,i.e.,
`1 "volt" = (1 "joule")/(1 "coulomb")` or `1 V = (1 J)/(1 C) = 1 JC^-1`.
