A coil has an inductance of 0.2 H. When connected to an AC source of 50 Hz, what is its inductive reactance?
Q1. A coil has an inductance of 0.2 H. When connected to an AC source of 50 Hz, what is its inductive reactance?
Answer: 62.8 ohms
Explanation: X_L = 2πfL = 2 * 3.14 * 50 * 0.2 = 62.8 ohms. Option B is incorrect due to wrong calculation.
