Inductive Reactance (XL) is measured in which unit?

Inductive reactance (XL) is a measure of the opposition that an inductor presents to alternating current (AC) due to its inductance. It is an essential concept in electrical engineering and is calculated using the formula XL = 2πfL, where f represents frequency and L stands for inductance.

The unit of inductive reactance is ohms. This is consistent with the fact that reactance, whether inductive or capacitive, is a type of impedance and is measured in the same units as resistance, which is also ohms. Resistance and reactance are both forms of opposition to current flow in an electrical circuit, making ohms the appropriate unit for both.

This understanding helps in analyzing AC circuits, as inductive reactance plays a crucial role in their behavior. In contrast, the other units presented—watts, amperes, and volts—relate to power, current, and voltage, respectively, rather than the specific opposition presented by inductors in AC circuits.
