capacitors, plural;
  1. A device used to store an electric charge, consisting of one or more pairs of conductors separated by an insulator

  1. (capacitor) an electrical device characterized by its capacity to store an electric charge
  2. A capacitor (formerly known as condenser) is a passive electronic component consisting of a pair of conductors separated by a dielectric (insulator). ...
  3. (capacitor) An electronic component capable of storing an electric charge; especially one consisting of two conductors separated by a dielectric
  4. (Capacitor) An electrical storage device used to start motors (start capacitor) and to improve the efficiency of motors (run capacitor).
  5. (capacitor) Electronic component which stores energy and then discharges it; blocks DC and allows AC to pass through.
  6. (Capacitor) An electrical device for accumulating and holding a charge of electricity. A capacitor is usually found in an electronic ignition system.
  7. (Capacitor) An electrical device that provides reactive power to the system and is often used to compensate for inductive reactive load to improve system power factor.
  8. (capacitor) A device that consists of two aluminum plates with an insulator between the plates; used to boost the starting torque of single-phase motors. The two types of capacitors are electrolytic or starting, and running or oil filled.
  9. (Capacitor) A device that stores electrical energy. Used on single phase motors.
  10. (Capacitor) Two conducting surfaces separated by a dielectric material. The capacitance is determined by the area of the surfaces, type of dielectric, and spacing between the conducting surfaces.
  11. (CAPACITOR, (CONDENSER)) A device that can store an electric charge when voltage is applied.
  12. (Capacitor) A device that stores electrical charges and can be used to maintain voltage levels in power lines and improve electrical-system efficiency.
  13. (CAPACITOR) A component made of conducting plates separated by a dielectric. It is impermeable to DC and attenuated the flow of AC as the current frequency drops. They are often categorised by the type of dielectric used- polyester, polypropylene, mica, etc.
  14. (CAPACITOR) A piece of equipment used to absorb surges or swells or to alleviate voltage sag occurring in a distribution system.
  15. (CAPACITOR) [Electrical]: The person designated to drive on a PUB crawl. "Whilst everyone was incapacitated, Homer was the capacitor in his ability to have all arrive safely at the next PUB." [Fishe]
  16. (Capacitor (C)) Electronics: A component constructed using two metallic plates separated by a dielectric and used to store electricity while under load. Capacitors are used in a circuit to allow for a variable current while maintaining a constant voltage. ...
  17. (Capacitor (Cap)) The ‘backup power’ of a ship, the capacitor, or cap, holds a certain amount of energy that can be exhausted by modules fitted to the ship. The amount of energy a module requires, depends on the module and the player’s skills. ...
  18. (Capacitor) A basic electronic component which acts as a reservoir for electrical power in the form of voltage. A capacitor thus acts to "even out" the voltage across its terminals, and to "conduct" voltage changes from one terminal to the other. ...
  19. (Capacitor) A component in circuitry which stores and releases voltage within the circuit. Also a type of microphone. See also microphones.
  20. (Capacitor) A component in crossover networks. Available at electronic supply stores. Capacitance is denominated in Farads. A cousin of a resistor, but presents a high resistance to low frequencies, and low resistance to high frequencies. Perversely, more capacitance means less resistance.
  21. (Capacitor) A device that stores electrical charge, using a positively charged surface and a negatively charged surface with a gap between them. The Leyden jar, used by early electrical experimenters (including Benjamin Franklin) was a form of capacitor. ...
  22. (Capacitor) A device used to store and release electricity, usually as the result of a chemical action. Also referred to as a storage cell, a secondary cell, a condenser or an accumulator. A Leyden Jar was an early example of a capacitor.
  23. (Capacitor) A device used to store charge. In audio systems, a capacitor stores energy during intervals that require less energy supply and release it when demands are higher than what is available from the power supply.
  24. (Capacitor) A pair of parallel "plates" separated by an insulator (the dielectric). Stores an electric charge, and tends to pass higher frequencies more readily than low frequencies. Does not pass direct current, and acts as an insulator. Electrically it is the opposite to an inductor. ...
  25. (Capacitor) A passive component that stores a charge, measured in Farads (F); capacitors resist changes in voltage, and are an essential component in (for example) power supplies for filtering out unwanted ac noise from a dc signal.
