Capacitors. Capacitors (historically known as condensators) are used to store a small amount of energy in an electrical field. Ideal capacitors do not dissipate their energy. The charge stored in a capacitor is known as capacitance. The unit for capacitance is the farad. One farad is equal to 1 joule per square volt, or 1 coulomb per volt.
