|
C sometime depend on the potential difference across the capacitor

Detailed explanation-1: -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-2: -In that equation, C is a constant. i.e., Q and V will always change by the same factor and cancel out. Therefore it doesn’t depend on the charge on the plates or the potential difference between them.
Detailed explanation-3: -The capacitance of a parallel plate capacitor depends on area of each plate, dielectric medium between the plates and distance between the plates.
Detailed explanation-4: -The capacitance does not depend on the charge between the plates.
