E is directly proportional to c and c is is proportion to permittivity. And mica having higher permittivity than other.

What is permittivity ?

What is permittivity?

It is directly related to electric susceptibility, which is a measure of how easily a dielectric polarizes in response to an electric field. It's shows ability of the material to passes the number of electric lines(imaginary lines) through the material.
