The expressions for charge, capacitance and voltage are given below.

How much electrical charge can a capacitor store on its plates?

The amount of electrical charge that a capacitor can store on its plates is known as its Capacitance value and depends upon three main factors. Surface Area – the surface area, A of the two conductive plates which make up the capacitor, the larger the area the greater the capacitance.

The capacitance is the amount of charge stored in a capacitor per volt of potential between its plates. Capacitance can be calculated when charge Q & voltage V of the capacitor are known: C = Q/V

How do you calculate charge of a capacitor?

C = Q/V, Q = CV, V = Q/C Thus charge of a capacitor is directly proportional to its capacitance value and the potential difference between the plates of a capacitor.Charge is measured in coulombs. One coulomb of charge on a capacitor can be defined as one farad of capacitance between two conductors which operate with a voltage of one volt.

How does a capacitor charge a battery?

When a capacitor charges, electrons flow onto one plate and move off the other plate.
