Question

What happens to the reactance in a purely inductive load if we increase the driving angular frequency?

Answer 1

The reactance in a purely inductive load if we increase the driving angular frequency will also increase .

An inductor is defined as a passive component that is used in most electrical circuits to store energy in the form of magnetic energy when electric current flows through it. It is also known as the coil, choke, or reactor. It is a two-terminal electrical component that is characterized by its inductance.

Inductive reactance is the property of an inductive coil that resists the change in alternating current (AC) through it and is similar to the opposition to direct current (DC) in a resistance.

Inductive reactance = angular frequency * inductance

X (L) = ω L

The inductive reactance of an inductor is directly proportional to  angular frequency . Hence , if reactance in a purely inductor increases if there is an increase in angular frequency .

The slope shows that the “Inductive Reactance” of an inductor increases as the supply frequency across it increases. Then we can see that at DC an inductor has zero reactance (short-circuit), at high frequencies an inductor has infinite reactance (open-circuit).
