What is the unit of measure for inductive reactance?

Inductive reactance is a measure of how much an inductor resists the change in current in an alternating current (AC) circuit, and the unit used to express this resistance is the ohm. Specifically, inductive reactance (denoted as (X_L)) can be calculated using the formula:

[

X_L = 2 \pi f L

]

where (f) is the frequency of the AC signal in hertz, and (L) is the inductance in henries. The resulting value (X_L) is expressed in ohms, which is the standard unit for measuring both resistance and reactance in electric circuits.

Other choices represent different electrical properties: the henry is the unit of inductance, the farad is the unit of capacitance, and the volt is the unit of electrical potential. Thus, the only correct unit for measuring inductive reactance is the ohm.
