Question

Quizplus · Accepted Answer

The capacitance of a capacitor is defined as the ratio of the charge on one of its plates to the potential difference between the plates, and it is independent of the charge on the capacitor. Capacitance depends on the physical characteristics of the capacitor (like plate area and separation, and the dielectric material between the plates) but not directly on the amount of charge on the plates.
