In what unit is the inductive reactance of a coil measured?

The inductive reactance of a coil is measured in Ohms. Inductive reactance refers to the opposition that an inductor presents to the alternating current (AC) due to its inductance. It is a critical parameter when analyzing circuits that contain inductors, especially in the context of AC systems.

The reason Ohms is the appropriate unit for inductive reactance is that it represents resistance in an electrical context, where impedance (which includes both resistance and reactance) is also measured in Ohms. This makes it relevant for understanding how inductors behave in circuits under AC conditions.

In contrast, the other options relate to different electrical or magnetic concepts. Mhos represents electrical conductance, which is not applicable here; Henrys is the unit of inductance itself, not reactance; and Gauss measures magnetic field strength, which does not pertain to the impedance experienced by AC in an inductor. Thus, Ohms is the standard unit for measuring inductive reactance.
