Question

what do you mean by dielectric constants​

Answer 1

Answer:

Dielectric constant (ϵr) is defined as the ratio of the electric permeability of the material to the electric permeability of free space (i.e., vacuum) and its value can derived from a simplified capacitor model. The dielectric constant is the ratio of the permittivity of a substance to the permittivity of free space.it's unit f/m.

The dielectric constant is a measure of the amount of electric potential energy, in the form of induced polarization that is stored in a given volume of material under the action of an electric field. It is expressed as the ratio of the dielectric permittivity of the material to that of a vacuum or dry air.
