Energy storage, provision of flexible filter options, power conditioning and coupling are some applications of a capacitor. Together with resistors, capacitors are used as main elements of frequency selective filters. More »

A spherical capacitor consists of two hollow, concentric spheres of oppositely charged electrodes with an insulator in between them. Physicists consider Earth to be a huge spherical capacitor surrounded by the ionosphere... More »

Energy, the ability of a system to do work, has a variety of measurement units, but the most basic unit of energy is the joule. Named after James Joule, the joule was developed to explain the relationship between heat an... More »

Energy transfer is the conveyance of energy from one item to another; the transfer occurs among different scales and motions. Energy transfer may mean different things in different sciences. More »
