Given the load circuit in Figure P16-3, find the complex power delivered to the load impedance \(Z\), when:

(a) \(\mathbf{V}=150<45^{\circ} \mathrm{V}(\mathrm{rms}), Z=50+j 50 \Omega\)

(b) \(Z=30<75^{\circ} \Omega\), I \(=10<-25^{\circ} \mathrm{A}(\mathrm{rms})\)

(c) \(\mathbf{V}=100<0^{\circ} \mathrm{V}(\mathrm{rms}), 50 \mathrm{~Hz}\) across a \(50-\Omega\) resistor in series with a \(100-\mathrm{mH}\) inductor.
