Question

a capacitor stores 60 microC charge when connected across a battery. When gap between plates is filled with dielectric , a charge of 120microC flows through battery. calculate the dielectric constant of the material inserted.?????

Answer 1

Dielectric constant is :

The ratio of the field without dielectric to the field with dielectric.

This is denoted by :

k = E₀ / E

In our case :

E ₀ = Field with dielectric

= 120

E = field without dielectric

= 60

k = 120/60 = 2

Answer :

2
