Question

Difine electric potential at a point.Obtaine a n expression for the electric potential at a point due to a point charge.

Answer 1

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

potential difference between two points is said to be 1 volt if work done in transferring 1 coulomb of charge from one point to the other point is 1 Joule
potential difference is a scalar quantity
