# Formula Capacitor Electrical energy    Capacitance    Voltage

## Electrical energy

Unit
Energy stored, for example, in the electric field of a plate capacitor. The formula also applies to other charged bodies to which a capacitance $$C$$ can be assigned.

## Capacitance

Unit
Capacitance is a measure of how well a body can store charge. For example, how well the plate capacitor can store charge on its plates.

## Voltage

Unit
Voltage, for example, between the electrodes of a plate capacitor.
