☑ Formula For Reactance Of An Inductor

As frequency increases inductive reactance increases. Both are denoted by capital letter x with a subscript of l for the inductor and c for the capacitor.

Inductance Inductive Reactance Equations

The inductive reactance of an inductor is dependent upon its inductance as well as the frequency that is applied.

Formula for reactance of an inductor. It is possible to express this as a formula to calculate the reactance at a particular frequency. Formula for inductive reactance. The reactance increases linearly with frequency.

This means the eight henry inductor does not impede the dc signal at all. Using the formula xl 2pfl the reactance can be computed for frequencies of 50 100 500 and 1000 hz. Inductive reactance is measured in ohms just like resistance and can be calculated with the following formula.

A partial graph of the results shows the linear increase of reactance as the frequency is increased. The formula for calculating inductor reactance is. The inductive reactance of an inductor depends on its inductance and the frequency that is applied.

Formula to calculate the inductive reactance. Inductive reactance of a coil depends on the frequency of the applied voltage as reactance is directly proportional to frequency so far we have looked at the behaviour of inductors connected to dc supplies and hopefully by now we know that when a dc voltage is applied across an inductor the growth of the current through it is not instant but is determined by the inductors self induced or back emf value. Reactance has two types.

Inductive and capacitive reactance. As the name suggests the inductor provided opposition is called inductance reactance where opposition by the capacitor is called capacitive reactance. The reactance increases linearly with frequency.

Where x l is equal to the value of the inductor reactance or impedance in ohms f is equal to the frequency of the signal passing through the inductor in hz and l is equal to the value of the inductance of the inductor. It is possible to express this as a formula to calculate the reactance at a particular frequency. Xl inductive reactance on ohms.

The inductive reactance of an inductor increases as the frequency across it increases therefore inductive reactance is proportional to frequency x l a f as the back emf generated in the inductor is equal to its inductance multiplied by the rate of change of current in the inductor. Here the symbol x l represents the inductive reactance in ohms f represents the frequency of the signal in hertz cycles per second and l equals the inductance in henrys.
