Chapter 31: Problem 52
In an \(L-R-C\) series circuit, the phase angle is 40.0\(^\circ\), with the source voltage leading the current. The reactance of the capacitor is 400 \(\Omega\), and the resistance of the resistor is 200 \(\Omega\). The average power delivered by the source is 150 W. Find (a) the reactance of the inductor, (b) the rms current, (c) the rms voltage of the source.
