In a series R-L-C circuit, the phase angle is 40.0, with the source voltage leading the current. The reactance of the capacitor is 400 and the resistance of the resistor is 200 . The average power delivered by the source is 150 .
A) Find the reactance of the inductor.
B) Find the rms current.
C) Find the rms voltage of the source.
