Question
An inductor connected to an a.c. source 24V, 50Hz. If the inductor causes a current of 0.5A to flow out of the source, determine the inductance of the inductor.
Correct Answer
Option D is the correct answer.
Detailed Explanation
X_L = V/I = 24/0.5 = 48Ω, and L = X_L/(2πf) = 48/(2π×50) ≈ 0.153H.
Hint
Find reactance first (V/I), then convert to inductance using X_L = 2πfL.
