A common model for a practical inductor is a coil resistance in series with an inductance L. The coil resistance accounts for the internal losses of an inductor. Figure P4.53 shows an ideal capacitor in parallel with a practical inductor. Determine the current supplied by the source vS . Assume:
vS (t) = Vo cos(?t + 0)
Vo = 10V ? = 6Mrad/s RS = 50 ?
RC = 40 ? L = 20?H C = 1.25 nF
