Can anyone tell the different types of inductors.
Iron core, laminated or ferrite Air core Toroidal Power frequency Radio frequency Fixed value Adjustable value Two terminal Multi-terminal or tapped
1 il inductor 2.parallel inductor 3.toroidal inductor are the some types of inductor
Your question is vague, but I will try to cover things. Plain inductors, which is a coil of wire, can be air core or wrapped around some metallic core. Metallic cores vary when developing audio inductors for noise suppression. Sometimes ferrite beads are all that is necessary which is a bead over a wire - an inductor with one turn. Inductors can be used to vary the phase of the current. They can be used as current limiters by way of their inductive reactance. When inductors are coupled you get transformer action, which brings up a whole topic of various transformers.
I'd like to add, that no-one uses inductors if at all possible to design them out lossy, costly, imprecise (too much resistance for a given size) Filters use R and C's (and opamps) or DSP in digital In power supplies, frequencies are moving into the 1MHz area so that they can use flat coils made into the pcb You can still buy inductors, basically two types tiny minature inductors with relatively high resistance for tuning and old fashioned filters or power inductors for switching regulators Powetr factor control or control of harmonics in power circuits or ballast (as in lighting)
