Question

define electric field and electric potential at a point and write relation between them expression only.​

Answer 1

Explanation:

In other words, the electric field is a measure of force per unit charge. The electric potential at a point is the quotient of the potential energy of any charged particle at that location divided by the charge of that particle. Its units are JC-1. Thus, the electric potential is a measure of energy per unit charge.

The electric field exists if and only if there is an electric potential difference. If the charge is uniform at all points, however high the electric potential is, there will not be any electric field. Thus, the relation between electric field and electric potential can be generally expressed as – “Electric field is the negative space derivative of electric potential.”
