An RLC series circuit is powered by a 120-V, 60-Hz supply. It contains an inductor that has an inductive reactance of 50 Ω and a wire resistance of 10 Ω . What is the inductance of the inductor?
A) 0.0265 H
B) 0.133 H
C) 0.259 H
D) 0.335 H

Question

Quizplus · Accepted Answer

The inductive reactance (X_L) is given by X_L = 2πfL, where f is the frequency and L is the inductance. Solving for L gives L = X_L / (2πf) = 50 / (2π * 60) = 0.133 H.
