What is the unit of measure for reactance in electrical circuits?

The unit of measure for reactance in electrical circuits is indeed the ohm. Reactance represents the opposition that an inductor or a capacitor offers to the flow of alternating current (AC) due to its inductive or capacitive properties, respectively. Just like resistance, which measures how much a component resists the flow of DC, reactance quantifies how much a component resists AC under specific frequency conditions.

In AC circuits, reactance can be calculated using the formulas for inductive reactance (XL = 2πfL) and capacitive reactance (XC = 1/(2πfC)), where f is the frequency, L is the inductance, and C is the capacitance. The results of these calculations are expressed in ohms, which is the standard unit of electrical resistance and reactance. Therefore, understanding that reactance is measured in ohms aligns with fundamental electrical principles concerning how both resistive and reactive components respond to electrical currents and fields.
