Question

Explain what is mearnt by
(i) the potential
(ii)the electric field strength at a point in an electric field. State and explain how these quantities are related.

Answer 1

Electric potential is defined as the amount of work required to move a unit charge from a one point to a another point against an electric field.

Electric Field defined as the electric force per unit charge. That is

$E=\frac{F}{q}$

The relation between the electric potential and the electric field is

$E=- \nabla V$
