Inductor is an electrical device ,used in various circuits because of it’s property of inducing magnetic charge .Inductor consists of wire loop or coil which has the ability to oppose the flow of current through it. Its function is to introduce inductance [resist flow of current] into a circuit.
The property of inductor to oppose current flow or its inductance is dependent on the number of turns of the coil, its core and length of the coil.
Since, inductors have the ability to delay flowing current, they are the basic electronic component used in electronics where current and voltage change frequently.
There are three different types of inductors commonly known which fixed, variable and adjustable inductors .
1. Fixed conductors are used in household devices, radios, TV etc.
2. Variable inductors are used in variable inductors, where you can control inductance as it consists of different moving parts which allow scope for more control.
3. Adjustable inductors- they have different points which provide different inductance as per the requirement.
Inductors are used for varied functions in different electronic devices .They are used as protectors or absorbers because they can block strong current changes. It’s basic importance is that, they are used in construction of transformers and they are commonly used in devices like radio to lower the interference.
