Find the equivalent impedance z when omega 2000 rads

Question

1. Using standard values from theinside rear cover, select values of components that will yield Z_L = 80∠45° Ω ± 5% at 5 kHz.

2. For the circuit of Figure.

(a) Find the equivalent impedance Z when ω = 2000 rad/s. Express the result in both polar and rectangular forms.

(b) Select standard values from the inside rear cover to realize the results ± 10% from part (a).
