Inductor

 Inductor :

                    Inductor is a simple copper wire which has two terminals that stores energy in a magnetic field when electri current supply.

Symbol :-

                

Types of Inductor :-

* Air core Inductor.

* Inductor with iron core.

* Toroidal Inductor.

* Inductor with ferrite core.

* Multi layer ceramic Inductor.

Working principle :-

When we supply DC power to inductor circuit it's produced magnetic field and if we cut-off power supply no magnetic field in the circuit.

Similarly, when we supply AC power to inductor circuit energy produced in the form of magnetic waves like radio frequencies, Tv signal etc..

Application of Inductor :-

• It is used in tuning circuits for radio frequencies.

• It is used in filter signal circuits.

• It is used for impedance matching.

• It is used for high frequency application includes TV and radio receivers.

• It is used in oscillator circuits.

• It is used for inter-stage coupling.

Note : 

this is a small topic to understand Inductor.
