What is capacitor ?
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 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 or theDRAM willlose its data.
Large capacitors are used in the power supplies of electronicequipment ofall types, including
computers and their peripherals. In these systems,thecapacitors smooth out the rectified utility AC,
providing pure, battery-likeDC.
