A

area of the plate is decreased

B

distance between the plates increases

C

area of the plate is increased

D

dielectric constant decreases.

Text Solution

Verified by Experts

The correct Answer is:
C
In a parallel plate capacitor the capacity of capacitor .
`C = (K epsi_(0)A)/(d) i.e., C propA`
The capacity of capacitor increases if area of the plate is increased.
