Expert Answer:

A capacitor is a device that is used to store energy. For instance normally you use a battery as a source of energy. You can charge a capacitor and keep it and then later on use it, instead of a battery, to provide current in a circuit. Apart from this it is an important circuit element in many ac circuits. There it helps to control the current in the circuit.

Please tell us specifically what you need to know about capacitors. You can read through capacitors in your textbook and then ask us what you do not understand.
