In this topic, you study Types of Inductor.
All inductors can be classified into two general categories: fixed and variable.
Variable Inductor
A variable inductor has some arrangement with the help of which flux linkages of the coil and thereby its inductance is changed. For example, it may have a ferromagnetic core or shaft that can be moved within the coil, or it may have a tapped coil.
Fixed Inductor
On the other hand, inductance of a fixed inductor cannot be changed by the user.
The fixed inductors are of following types.
- Air core inductors,
- Iron core inductors and
- Ferrite core inductors.
Applications of Inductor
These applications include carrier telephony, domestic television receivers, domestic radio receivers, wide-band pulse transformers, oscillators, signal generators, high-frequency amplifiers, etc.
