Vedclass · Answer

(B) The maximum electric field intensity that a dielectric material can withstand without breaking down (i.e.,becoming conducting) is known as its dielectric strength.Since the electric field $E$ is defined as the potential gradient,$E = -\frac{dV}{dr}$.When the potential gradient reaches a critical value,the dielectric material undergoes electrical breakdown,which is referred to as the dielectric strength of the material.

The potential gradient at which the dielectric of a condenser just gets punctured is called

What is the dimensional formula for the intensity of polarization?

Assertion : In the absence of an external electric field,the dipole moment per unit volume of a polar dielectric is zero.
Reason : The dipoles of a polar dielectric are randomly oriented.
