A 20 mH inductor in series with a resistance of 55 ohms is connected to a source whose voltage is = 310 V cos 150πt, where t is in seconds.

(a) Determine the maximum current in the circuit. (I solved this already, I=5.63A)
(b) Determine the maximum and rms voltages across the inductor.
(c) Determine the average power dissipation.
(d) Determine the maximum and average energy stored in the magnetic field of the inductor.
