Question

In a parallel plate capacitor with increase in distance between the plates, its capacity ................

Answer 1

In general capacitance of parallel plate capacitor is given by:

$C=\frac{k{ϵ}_{0}A}{d}$

where C is capacitance, k is relative permittivity of dielectric material, ${ϵ}_0$ is permittivity of free space constant, A is area of plates and d is distance between them.

So as the distance between the plates is increased, its capacity decreases.
