The formula for inductive reactance can be expressed as what?

Inductive reactance is a measure of the opposition that an inductor presents to alternating current (AC) due to its inductance. The formula for inductive reactance is derived from the principles of AC circuits and is given by the expression ( X_L = 2πfL ), where ( X_L ) represents the inductive reactance, ( f ) is the frequency of the AC signal, and ( L ) is the inductance in henries.

As frequency increases, the inductive reactance rises proportionally, meaning the inductor will oppose the flow of AC more effectively at higher frequencies. This relationship signifies how inductors behave differently under AC conditions compared to direct current (DC), where they simply act as short circuits after a transient period.

The presence of the constant ( 2π ) in the formula relates to the conversion of frequency from hertz (cycles per second) to radians per second, making the term suitable for use in calculations involving sinusoidal waveforms typically found in AC circuits. Understanding this formula is crucial for linemen and electrical technicians, as it helps evaluate the performance of inductive components in various electrical systems.
