Question

define potential difference. write on expression for it.​

Answer 1

Explanation:

Electric potential difference between two points in an electric circuit is the work done to move a unit positive charge from one point to another. Potential difference v = W/q. The S.I unit of potential differences is 'volt' and denoted by V.
