The circuit in Figure P8-18 is operating in the sinusoidal steady state with \(\omega=100 \mathrm{krad} / \mathrm{s}\).

(a) Find the equivalent impedance \(Z\).

(b) What circuit element can be added in series with the equivalent impedance to place the circuit in resonance?

(c) Using the equivalent circuit found in part (a), add the new element found in part (b). Then using Multisim do an ac sweep of \(Z_{\mathrm{IN}}\). Using the cursor, detect the minimum and compare that value with the value calculated. How do they compare?
