How would you calculate the amount of energy stored in a capacitor?

The energy stored on a capacitor can be calculated from the equivalent expressions. This energy is kept in the electric field. Enter the voltage across the capacitor and the voltage across the capacitor and the capacitance of it. The change and energy are measured. W is the work measured joules. Q is the capacitance measured in frauds.

A capacitor can be able to store an electrical charge Q (units in Coulombs) of electrons. When a capacitor is fully charged there is a potential difference, p.d. Between its plates and the larger the area of plates and the largest the area of the plates and the smaller the distance between them (known as separation) the greater will be it’s capacitance.
