Scale the inductor and capacitor so that the
magnitude and the phase angle of the output current do not change when
the input frequency is changed from 20 krad/s to 500 rad/sec.
1. What are the scaled values of the inductor and capacitor?
2. What is the steady-state value of the output current, io, when the
input current is 400 cos 500t mA?
