At a fundamental level, capacitors are made of two electrodes (conductors, often metal) separated by a dielectric (insulator). When an electrical signal is applied to one of the electrodes, energy is stored in the electrical field between the two separated electrodes. The stored amount of energy is called ‘capacitance.’ When.
