OBJECTIVE

A capacitor is a passive two-terminal electrical component that stores electric energy in an electric field.

The forms, styles and materials of practical capacitors very widely, but all contain at least two electrical conductors (plates) separated by an insulating layer, the dielectric.

Capacitors are widely used as parts of electrical circuits in many common electrical devices.

WHAT IS CAPACITOR

•A device used to store charge in an electrical circuit. A

capacitor functions much like a battery, but charges and

discharges much more efficiently (batteries, though, can

store much more charge)

•But the many circuit phenomena generated by such a basic

charge and discharge action of extending make the

capacitor have various different purpose,for example, in the

electric motor and we use it to produce a phase shift in

photoflash

NOTES

CERAMIC pF - μF High - Multipurpose- Cheap

MICA pF - nF High - Expensive- Very stable

ELECTROLYTIC

High μF Low - Cheap- Hold charge for long time

POLYESTER High μF High - Cheap

PLASTIC High μF High - Cheap

ADVANTAGES DISADVANTAGES

Very good and faster in storing small quantities of electrical energy.

it absorbent energy from lightning shot altogether and keep charge in a few moments before discharge an energy again

can save the usage of electricity

charging electricity in usable capacitor to help main supply to be channelled to light burden like light

In series, can be cause of overcompensing voltage

In parallel, if one capacitor fails, it will not function

capacitor will damage when over charge  and  voltage imposed
