ALSO CALLED:
Ceramic Capacitors,
Condensers
DEFINITION: A capacitor is a passive electronic component that storesenergy in theform of an electrostatic field. In its simplest form, a capacitorconsists of twoconducting plates separated by an insulating material called thedielectric. Thecapacitance is directly proportional to the surface areas of the plates, andis inverselyproportional to the separation between the plates. Capacitance alsodepends on thedielectric

AC Vs. DC Power Distribution for Data Centers
sponsored by APC
WHITE PAPER:
In this paper, you'll learn why high-efficiency AC will likely emerge as the dominant choice for data center power distribution. Topics covered include a review of the characteristics of AC & DC distribution, A mathematical model of the efficiency of two different AC distribution systems, and Why many of the DC benefits are unfounded.

CAPACITORS DEFINITION (continued): … constant of the substance separating the plates.The standard unit of capacitance is the farad, abbreviatedF. Thisis a large unit; more common units are the microfarad, abbreviated µF (1 µF =10-6F) and the picofarad, abbreviated pF (1 pF = 10-12 F).Capacitors can be fabricated onto integrated circuit (IC)chips. They are commonly used in conjunction with transistors in dynamic random access memory (DRAM). The capacitors helpmaintain thecontents of memory. Because of their tiny physical size, thesecomponents have lowcapacitance. They must be recharged thousands of times per second … Capacitors definition sponsored by SearchCIO-Midmarket.com, powered by WhatIs.com an online computer dictionary
