2. Motor capacitor - Wikipedia

   en.wikipedia.org/wiki/Motor_capacitor

   Motor capacitors are used with single-phase electric motors [3]: 11 that are in turn used to drive air conditioners, hot tub/jacuzzi spa pumps, powered gates, large fans or forced-air heat furnaces for example. [1] A "dual run capacitor" is used in some air conditioner compressor units, to boost both the fan and compressor motors. [1]

3. Capacitor - Wikipedia

   en.wikipedia.org/wiki/Capacitor

   The maximum energy is a function of dielectric volume, permittivity, and dielectric strength. Changing the plate area and the separation between the plates while maintaining the same volume causes no change of the maximum amount of energy that the capacitor can store, so long as the distance between plates remains much smaller than both the ...

4. Fan coil unit - Wikipedia

   en.wikipedia.org/wiki/Fan_coil_unit

   A fan coil unit (FCU), also known as a Vertical Fan Coil Unit (VFCU), is a device consisting of a heat exchanger (coil) and a fan. FCUs are commonly used in HVAC systems of residential, commercial, and industrial buildings that use ducted split air conditioning or central plant cooling.

5. Electrolytic capacitor - Wikipedia

   en.wikipedia.org/wiki/Electrolytic_capacitor

   An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization.This oxide layer acts as the dielectric of the capacitor.

6. Applications of capacitors - Wikipedia

   en.wikipedia.org/wiki/Applications_of_capacitors

   Capacitors used for suppressing undesirable frequencies are sometimes called filter capacitors. They are common in electrical and electronic equipment, and cover a number of applications, such as: Glitch removal on direct current (DC) power rails; Radio frequency interference (RFI) removal for signal or power lines entering or leaving equipment

7. Variable-frequency drive - Wikipedia

   en.wikipedia.org/wiki/Variable-frequency_drive

   This power is returned to the drive's DC link element (capacitor or reactor). A DC-link-connected electronic power switch or braking DC chopper controls dissipation of this power as heat in a set of resistors. Cooling fans may be used to prevent resistor overheating. [34] Dynamic braking wastes braking energy by transforming it to heat.
