  2. Energy storage - Wikipedia

    en.wikipedia.org/wiki/Energy_storage

    Storage capacity is the amount of energy extracted from an energy storage device or system; usually measured in joules or kilowatt-hours and their multiples, it may be given in number of hours of electricity production at power plant nameplate capacity; when storage is of primary type (i.e., thermal or pumped-water), output is sourced only with ...

  3. Capacitor - Wikipedia

    en.wikipedia.org/wiki/Capacitor

    A capacitor can store electric energy when disconnected from its charging circuit, so it can be used like a temporary battery, or like other types of rechargeable energy storage system. [77] Capacitors are commonly used in electronic devices to maintain power supply while batteries are being changed.

    An electric lamp that generates light from an electric arc. arc welder A device used to join metals by melting them with an electric arc. armature That part of an electrical machine that converts electrical energy to mechanical energy (or vice versa). artificial intelligence A computer system that replicates some feature of human intelligence.

  5. Accumulator (energy) - Wikipedia

    en.wikipedia.org/wiki/Accumulator_(energy)

    An accumulator is an energy storage device: a device which accepts energy, stores energy, and releases energy as needed.Some accumulators accept energy at a low rate (low power) over a long time interval and deliver the energy at a high rate (high power) over a short time interval.

    The capacitor is a development of the Leyden jar and is a device that can store charge, and thereby storing electrical energy in the resulting field. It consists of two conducting plates separated by a thin insulating dielectric layer; in practice, thin metal foils are coiled together, increasing the surface area per unit volume and therefore ...

    Musschenbroek's outlet in France for the sale of his company's 'cabinet' devices was the Abbé Nollet (who started building and selling duplicate instruments in 1735 [17]). Nollet then gave the electrical storage device the name "Leyden jar" and promoted it as a special type of flask to his market of wealthy men with scientific curiosity.
