The relationship between frequency and inductive reactance (Xl) is directly proportional. Inductive reactance is defined by the formula Xl = 2πfL, where "f" is the frequency of the alternating current (AC) and "L" is the inductance measured in henries. This formula illustrates that as the frequency increases, the inductive reactance also increases, provided the inductance remains constant. Therefore, if you were to double the frequency, the inductive reactance would also double, indicating a direct proportionality.

This understanding is crucial in power system operations, especially regarding the behavior of inductive loads in AC circuits, where changes in frequency can significantly affect reactance and consequently influence system stability and operation.
