True or False question: Please answer whether it is correct or incorrect. 3 points for a correct answer, 2 points for an incorrect answer, and 5 points for a detailed explanation of the reason. In AC circuits, the inductive reactance of an inductor is proportional to the power supply frequency and the inductance coefficient.
Correct. The magnitude of the inductive reactance is related to the frequency f of the alternating current and the inductance L of the coil. When the frequency is constant, the inductive reactance is proportional to the inductance ； When the inductance is constant, the inductive reactance is proportional to the frequency. XL=2πfL
