Inductive reactance is measured in which unit?

Inductive reactance is correctly measured in ohms. This unit is derived from the same principles that apply to resistance in an electrical circuit; however, inductive reactance specifically pertains to the opposition that an inductor presents to alternating current (AC) due to the inductance property.

Inductive reactance arises from the magnetic fields created by an inductor when alternating current flows through it. This impedance is frequency-dependent and is calculated using the formula (X_L = 2\pi f L), where (X_L) is the inductive reactance, (f) is the frequency, and (L) is the inductance in henries. Since ohms is the standard unit of measurement for any form of electrical opposition to current flow, it is used to express both resistance and reactance.

In this context, volts measure electrical potential, farads measure capacitance (the ability of a system to store charge), and amps measure current. These units serve different purposes in electrical theory and do not directly correspond to the opposition an inductor provides to AC as measured by inductive reactance. Thus, ohms is the only correct unit for this specific measurement.
