Building codes throughout the United States prohibit residential ceiling fans from being mounted with the blades closer than seven feet from the floor; [22] this sometimes proves, however, to not be high enough. If a ceiling fan is turned on and a person fully extends his or her arms into the air, as sometimes happens during normal tasks such ...
A typical motor start capacitor. A motor capacitor [1] [2] is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field. [citation needed] There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run ...
The reactive power produced by a capacitor bank is in direct proportion to the square of its terminal voltage, and if the system voltage decreases, the capacitors produce less reactive power, when it is most needed, [2] while if the system voltage increases the capacitors produce more reactive power, which exacerbates the problem. In contrast ...
A glitch (circled in red) occurring during circuit operation. Glitch removal is the elimination of glitches—unnecessary signal transitions without functionality—from electronic circuits.
In many applications of capacitors dielectric absorption is not a problem but in some applications, such as long-time-constant integrators, sample-and-hold circuits, switched-capacitor analog-to-digital converters, and very low-distortion filters, the capacitor must not recover a residual charge after full discharge, so capacitors with low ...
Capacitors used after a voltage regulator to further smooth DC power supplies; Capacitors used in audio, intermediate frequency (IF) or radio frequency (RF) filters (e.g. low pass, high pass, notch, etc.) Arc suppression, such as across the contact breaker or 'points' in a spark-ignition engine

A thyristor-switched capacitor (TSC) is a type of equipment used for compensating reactive power in electrical power systems. It consists of a power capacitor connected in series with a bidirectional thyristor valve and, usually, a current limiting reactor ( inductor ).
