Capacitance is the ability of a system to store an electric charge. It is defined as the ratio of the electric charge (Q) stored on one plate of a capacitor to the voltage (V) across the plates. The unit of capacitance is the farad (F), which indicates how much charge a capacitor can store per volt. Capacitors consist of two conductive plates separated by an insulating material, known as a dielectric. When a voltage is applied, an electric field forms between the plates, allowing the capacitor to store energy.
