In a circuit a faulty capacitor causes a malfunction and must be changed with another one of the same capacity.

A capacitor accumulates electrical charge inside, which can be released into a circuit. It’s formed by two faces of a conductive material, divided by an insulating material. When a voltage generator is connected, the electrical charges situated in the insulator moves towards to the conductive faces, which charge themselves with negative and positive charges. This property of a capacitor is called capacitance, and the unit to measure is Farad.
