An AC source supplies (230\text{ V rms}\) at (50\text{ Hz}\) to a series circuit containing a resistor \(R\) and an ideal inductor \(L\). The magnitude of the total impedance is \(250\ \Omega\) and the real power consumed is \(150\text{ W}\). Determine the resistance \(R\) (in ohms, to the nearest whole ohm) and the inductance \(L\) (in henries, to two decimal places).

Answer Options

A. R ≈ 150 Ω, L ≈ 0.70 H
B. R ≈ 165 Ω, L ≈ 0.60 H
C. R ≈ 200 Ω, L ≈ 0.45 H
Correct Answer D. R ≈ 177 Ω, L ≈ 0.56 H
Correct Answer
D
Correct Option:
R ≈ 177 Ω, L ≈ 0.56 H
