Abstract

A capacitor is a device that stores electric energy between a pair of electrodes on which electric charges (Q in Coulomb) accumulate. Historically, capacitors have taken the form of a pair of thin metal plates, which are either flat or tightly wound up in a cylinder having capacitance (C). This is a measure of the potential difference or voltage (V), which appears across the plates for a given amount of energy stored on each plate (Q/V in a unit of Farad). A traditional parallel-plate capacitor stores the amount of energy that is proportional to the surface area (A) of the conducting plate and inversely proportional to the distance (d) between the plates. It is also proportional to the permittivity of the dielectric substance that separates the plates, whether vacuum, air, or electrically insulating materials chosen for their special dielectric characteristics.
