- The Inductor is also called as a choke. It is another passive type electrical component which is just a coil of wire that is designed to take advantage of this relationship by inducing a magnetic field in itself or in the core as a result of the current passing through the coil.
- A passive component which has the ability to store the magnetic field is called “inductor”. Inductor has property to pass Cand oppose A.C.
- Inductor is nothing more than a coil of a wire wound around a central core. For most coils the current flowing through the coil produces a magnetic flux around it that is proportional to this flow of electrical current.
- Inductors are formed with wire tightly wrapped around a solid central core which can be either a straight a cylindrical rod or a continuous loop or ring to concentrate their magnetic flux.
- Inductors resist or oppose the changes of current but will easily pass a steady state DC current.
- This ability of an inductor to resist changes in current and which also relates current with its magnetic flux linkage as a constant of proportionality is called inductance.
- Inductance is the property of an electrical circuit where by changes in the current flowing through it causes change in the magnetic field. The unit of inductance is Henry(h).
