How does a capacitor work?

A capacitor consists of two parallel conducting plates separated by an insulator.

The charge flow and the final charge on each plate is shown in the diagram.

What happens when a capacitor is connected to a voltage supply?

When capacitors in series are connected to a voltage supply: because the applied potential difference is shared by the capacitors, the total charge stored is less than the charge that would be stored by any one of the capacitors connected individually to the voltage supply. The effect of adding capacitors in series is to reduce the capacitance.

The capacitors ability to store this electrical charge ( Q ) between its plates is proportional to the applied voltage, V for a capacitor of known capacitance in Farads.
