A capacitor consists of two parallel conducting plates separated by an insulator. When it is connected to a voltage supply charge flows onto the capacitor plates until the potential difference across them is the same as that of the supply. The charge flow and the final charge on each plate is shown in the diagram.
The higher the value of capacitance, the more charge the capacitor can store. The larger the area of the plates or the smaller their separation the more charge the capacitor can store. A capacitor is said to be “Fully Charged” when the voltage across its plates equals the supply voltage.
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.
When a voltage V is applied to the capacitor, it stores a charge Q, as shown. We can see how its capacitance may depend on A and d by considering characteristics of the Coulomb force. We know that force between the charges increases with charge values and decreases with the distance between them.
A charged capacitor can supply the energy needed to maintain the memory in a calculator or the current in a circuit when the supply voltage is too low. The amount of energy stored in a capacitor depends on: the voltage required to place this charge on the capacitor plates, i.e. the capacitance of the capacitor.
A capacitor stores electric charge. It’s a little bit like a battery except it stores energy in a different way. It can’t store as much energy, although it can charge and release its energy much faster. This is very useful and that’s why you’ll find capacitors used in almost every circuit board.
