Consider a capacitor of capacity C. When a certain charge is given to it, it is raised through a certain potential. In order to add more charge to it, the new installment of charge has to be brought against the force of repulsion due to the charge already present upon it. Therefore, some work has to be done by the external agency.
The addition of new charge raises, further, the potential of the capacitor. Since, the additional installments of charge brought to the capacitor are against gradually increasing potential, so greater amount of work has to be done. The total work done to increase the charge on a capacitor from zero to a desired value gets stored in it and is known as the potential energy of the capacitor.
