A circuit consists of an ideal ac generator, a 20 µF capacitor, and an 90? resistor, all connected in series. The output of the generator has a peak emf of 20 V, and the armature of the generator rotates at 300 rad/s.
(a) Find the power factor.
(b) Find the rms current.
mA(c) Find the average power supplied by the generator.
