Question

The circuit is scaled so that the 100 Ω resistor is replaced by 500 Ω resistor and the 160 μH inductor is replaced by a 2
mH inductor.
1. What is the scaled value of the capacitor?
2. Find the frequency for which the impedance Zab is purely resistive
for the scaled circuit.
3. How is the frequency you found in part (b) related to the frequency
for which the impedance Zab is purely resistive in the un-scaled
circuit?
