Learn more WhatsAppA capacitor is a device used to store charge. The amount of charge (Q) a capacitor can store depends on two major factors—the voltage applied and the capacitor''s physical characteristics, such as its size. The capacitance (C) is the amount of charge stored per volt, or (C=dfrac{Q}{V}.)
