In a parallel plate capacitor, the capacity can be increased by decreasing

A
permeability of the medium.
B
value of dielectric constant.
C
area of the plates.
Correct answer
D
the distance between plates.

Solution

Separation. Decreasing the separation of the plates, decreases the voltage of the capacitor since the electric-field is not affected by the distance between the plates. The voltage on the capacitor is $V=E d$. Therefore the voltage increases

Hence, the correct answer is option: 'D'.
