An inductor has an inductive reactance of 64 Ω , and a wire resistance of 36 Ω . What is the impedance of the inductor?
A) 10 Ω
B) 28 Ω
C) 73.4 Ω
D) 82.92 Ω

Question

Quizplus · Accepted Answer

The impedance of an inductor is calculated using the formula $Z = \sqrt{R^2 + X_L^2}$, where $Z$ is the impedance, $R$ is the resistance, and $X_L$ is the inductive reactance. Substituting the given values, $Z = \sqrt{36^2 + 64^2} = \sqrt{1296 + 4096} = \sqrt{5392} ≈ 73.4 \Omega$.
