Question
A series ac circuit is shown. The inductor has a reactance of 90 ohms and an inductance of 240 mH. A 80 ohm resistor and a capacitor whose reactance is 140 ohms are also in the circuit. The rms current in the circuit is 1.6 A. In the figure, the peak magnetic energy in the inductor is closest to:
