Question:

Losses in real inductors can be modeled by a series resistor as shown in Figure P7-7.3 . In this problem, we include the effect of this resistor on the design of the series $R L C$ circuit shown in the figure. The design requirements include a source resistance of

$50 \Omega$, an undamped natural frequency of $50 \mathrm{kHz}$, and a damping ratio less than 0.1.
The characteristics of the available inductors are listed below.
