QUESTION:

The input to the circuit shown in Figure DP 10-6 is the voltage source voltage

                                                                       \(v_{\mathrm{s}}(t)=10 \cos (1000 t) \mathrm{V}\)

The output is the steady-state capacitor voltage

                                                                     \(v_{\mathrm{o}}(t)=A \cos (1000 t+\theta) \mathrm{V}\)

(a) Specify values for R and C such that \(\theta=-30^{\circ}\). Determine the resulting value of A.

(b) Specify values for R and C such that A = 5 V. Determine the resulting values of \(\theta\).

(c) Is it possible to specify values for R and C such that A = 4 and \(\theta=-60^{\circ}\)? (If not, justify your answer. If so, specify R and C.)

(d) Is it possible to specify values of R and C such that A =  7.07 V and \(\theta=-45^{\circ}\)? (If not, justify your answer. If so, specify R and C.)
