Question

On keeping dielectric plate in between an air capacitor of 2uf capacitance, its capacitance becomes 5uf. Determine the dielectric constant of the material​

Answer 1

Explanation:

The capacitance of a capacitor when dielectric constant K is introduced is

C=KC'

where C' is the capacitance without dielectric constant.

So,

5 = K×2

K = 2.5
