Types of Inductor:
Inductors can be categorised as :
1. Fixed inductors,
2. Variable inductors,
3. Preset inductors, and
Fixed inductors offer a fixed inductance while connected in an electrical circuit. Figure illustrated the circuit representation of fixed inductors. Fixed inductors are wound in such a manner that the number of turns do not charge and if it utilizes any core of magnetic material, iron core of ferrite, its position w.r.t. the winding remains fixed. Coils wound on toroidal cores are an instance of fixed inductors.
