A capacitor is a device used to store electrical charge and electrical energy. It consists of at least two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, they are "capacitor plates.") The space between capacitors may simply be a vacuum ...
A supercapacitor is a double-layer capacitor with very high capacity but with low voltage limits. Supercapacitors, compared to capacitors, have a larger area for storing more charge, with capacitance into the farad (F) range, and they store more energy than electrolytic capacitors. They have a low leakage current and are suitable for many ...
The formula for this relationship is: E = 1/2 * Q^2 / C. Where: – E is the energy stored in the capacitor (in joules) – Q is the charge stored on the capacitor (in coulombs) – C is the capacitance of the capacitor (in farads) This formula is useful when the charge on the capacitor is known, rather than the voltage.

The energy (U_C) stored in a capacitor is electrostatic potential energy and is thus related to the charge Q and voltage V between the capacitor plates. A charged capacitor stores energy in the electrical field between its plates.
Where E is the electric field, F is the force exerted on a particle introduced into the field and q is the charge of the particle. The unit for electric field is volts per meter [V·m-1] or newtons per coulomb [N·C-1]. Q Factor The quality factor or Q factor of a capacitor, represents the efficiency of a given capacitor in terms of its energy losses.
A capacitor is a device used to store electric charge. Capacitors have applications ranging from filtering static out of radio reception to energy storage in heart defibrillators. Typically, commercial capacitors have two conducting parts close to one another, but not touching, such as those in Figure 19.5.1.
