The amount of opposition an inductor creates in an ac circuit is dependent upon the inductance value and the frequency of the voltage source.

Inductors in ac circuits. In an ac circuit with an inductor the voltage across an inductor leads the current because of the lenz law. Hey guys in this video were going to talk about inductors and the role that they play in ac circuits. Inductors in an ac circuit inductive reactance.

As stated earlier inductor acts differently to ac comparing to dc signal source. An inductor will basically behave and produce a short across itself when subjected to a dc while offer an opposing or restricting response when applied with an ac. Current and voltage in an inductor are not in phase with each other.

Now remember that the current in an ac circuit at any time is going to be given by the equation that by now weve seen a bunch of times i max cosine of omega t. Alright lets get to it. The inductive reactance x l of a circuit is a measure of this opposition.

When ac signal is applied to inductor it produces a magnetic field which is varying in time because the current producing the field is varying in time itself. Alternating current in a simple inductive circuit is equal to the voltage in volts divided by the inductive reactance in ohms just as either alternating or direct current in a simple resistive circuit is equal to the voltage in volts divided by the resistance in ohms. Like capacitors inductors in ac circuits differ from resistors in two crucial ways.

Instead of having a resistance an inductor in an ac circuit has something called an inductive reactance. Xl2pi fl x l is inductive reactance w f is frequency hz l is inductance f. Ac inductance and inductive reactance the opposition to current flow through an ac inductor is called inductive reactance and which depends lineally on the supply frequency inductors and chokes are basically coils or loops of wire that are either wound around a hollow tube former air cored or wound around some ferromagnetic material iron cored to increase their inductive value called inductance.

The magnitude of this opposing response or force of an inductor to an ac or alternating current is called the reactance of the inductor. Inductors in ac circuits.
