what is an inductor used for
inductor is used in ckt because it will work as controling current device
An inductor will supply better current source.
The inductor is a component which produces inductance. This inductance which opposes any change of current through it, so if any changes occurred in an IC the output will be changed. so inductor is not used.
If you put iron in the core of an inductor, it will increase the inductance of the inductor. Iron has a higher permeability compared to air or other materials typically used in inductors, allowing the magnetic field to be more concentrated and increasing the efficiency of the inductor.
To improve the power factor
Since we know that inductance of an inductor depends on the length of inductor by the formula L=muAN*N/l, where l is the length of inductor. So by varying the length of inductor we say that inductance of inductor varies.
let us try.........
The inductor is basically used for induction in electronics domain. such in the transformer inductor cause the electromagnetic induction which cause the flux to link with secondary winding and generate the voltage on secondary winding.inductors are also used in tunned circuits.
A time-varying magnetic field can be used to induce a current in an inductor
The purpose of an inductor is to store and release energy in the circuit usually in order to induce a phase shift in the voltage or current passing through it. Inductor stores energy in the magnetic field.
The resistance of an inductor is generally referred to as the series resistance, sometimes noted as RL. Note that resistance is a DC measurement and that an "ideal" textbook inductor has an RL of 0. The reactance of an inductor is an AC measurement which measures the reaction of a component's current flow to an alternating voltage and is frequency dependent and directly proportional to the inductor's inductance, measured in Henrie's. The impedance is most commonly used when talking about inductors or capacitors and is a combination of resistance and reactance.
In an ideal inductor, no, there is no voltage induced across an inductor unless the current in the inductor is changing. However, since there are no ideal inductors nor power supplies, eventually an inductor will draw a constant current, i.e. the limit of the power supply; and, since no inductor has zero ohms at equilibrium, that current will translate to voltage.
