Question

what is dielectric constant for medium​

Answer 1

Answer:

The Dielectric constant (K) of the medium is the ratio of the permittivity of the substance (VA epsilon) to permittivity of the free space.

The dielectric constant of a medium is defined on the ratio of permittivity of medium to the permittivity of free space. The dielectric constant is also called the relative permittivity of medium εr = K = εoε T
