Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How is the capacitance (C) of a parallel-plate capacitor affected by the charge on the plates?
A
C depend on the charge on the plates
B
C is vanished when there are plates
C
C does not depend on the charge on the plates
D
C is accumulated on one side only
Explanation: 

Detailed explanation-1: -Note The capacitance of the parallel plate capacitor is directly proportional to the permittivity of the plates and area of the parallel plates and the capacitance of the parallel plate capacitor is inversely proportional to the distance between the two parallel plates.

Detailed explanation-2: -when the potential difference V is increased, charge on capacitors also increases such that the ratio Q/V, remains constant i.e. capacitance remains constant . Because capacitance depends upon plate area, medium between plates and distance between plates .

Detailed explanation-3: -Explanation: Here capacitance C is constant and it does not depend on the voltage applied and the charge of the plates. Because voltage and charge are directly proportional to each other, when voltage is increased charge on plates will increase by the same factor.
