What is Capacitor?

Capacitor :-

       Capacitor is the system consisting of two conductors having equal and opposite charges separated by an insulator or dielectric.

       The capacitance of the capacitor is the ratio of magnitude of charges on either of conductors to the magnitude of potential difference between two conductors.

       The ability of a conductor to store the an electric charge and electrical potential energy is called the capacitance of the capacitor.

Units:-

       The SI unit capacitance is farad. (which  is in honor of Michel Faraday )

Applications Of Capacotor :-

1)  Tuning in radio circuit.

2)   For smoothing rectified current in power supplies.

3)  For eliminating the sparkling of points, when they are open or  close in an ignition system of automobile engine.

4)  For the storage of the large amount of charge for  the use in nuclear reactors.

5)  It makes current flow continuous.

6) It used to store small amount of electric current in electric circuit. 

7) It is used for producing clear sound in amplifiers.
