The empty space between plates of a parallel plate capacitor is filled with a liquid of dielectric constant K. The capacitance of capacitor will now:

1. Increase by a factor K²
2. Decrease by a factor K²
3. Increase by a factor K
4. Decrease by a factor K

Correct answer: 3. Increase by a factor K

Parallel plate capacitor’s capacitance equation:

C = ϵA/d

Where ϵ is absolute permittivity of medium.
