Capacitor

  Capacitor :

                   It is an electronic component which is use to store an electric charge and also used as filter (filter the current).

Working principle of capacitor :-

Power Supply is ON, it charge a current in short time when the power supply is OFF it slowly discharge a current.

Types of capacitor :-

* Ceramic capacitor

* Electrolytic capacitor

Ceramic capacitor :-

• It is non-polarised capacitor.

• It smooth the fluctuation in current.

• It used as filter in circuit.

Electrolytic capacitor :-

• It is polarized capacitor.

• It blow the current in the store.

• It used as electric charge.

Example :

Capacitor size and value calculation :-

How to find out the capacitor value in easy way are as follows below figures :

Application of capacitor :-

* Energy storage

* Power Factor Correction

* Noise Filters

* Motor staters.
