What is the unit of measure for inductive reactance?

Inductive reactance is a measure of how much an inductor resists the change in current. It specifically relates to the frequency of the alternating current and the inductance of the coil. The unit of measure used for inductive reactance is Ohms, which is the standard unit for measuring impedance in electrical circuits.

In the context of AC circuits, inductive reactance can be calculated using the formula:

[ X_L = 2\pi f L ]

where ( X_L ) is the inductive reactance in Ohms, ( f ) is the frequency in hertz, and ( L ) is the inductance in henrys. This highlights that while inductance is measured in henrys, inductive reactance, which includes the effects of frequency, is expressed in Ohms.

The other options (Farad, Henry, and Volt) are associated with other electrical properties; Farads measure capacitance, Henries measure inductance, and Volts measure electrical potential or voltage. Each of these units contributes to different aspects of electrical and electronic theory but does not apply directly to the concept of inductive reactance itself. Thus, the appropriate unit for measuring inductive reactance is indeed Ohms.
