Let a series R-L-C network be connected to a source voltage \(V\), drawing a current \(I\).

(a) In terms of the load impedance \(Z=Z

(b) Express \(ho(t)\) in terms of \(\mathrm{P}\) and \(\mathrm{Q}\), by choosing \(i(t)=\sqrt{2} \mathrm{I} \cos \omega t\).

(c) For the case of \(Z=R+j \omega L+1 / j \omega c\), interpret the result of part

(b) in terms of \(\mathrm{P}\), \(\mathrm{Q}_{L}\), and \(\mathrm{Q}_{C}\). In particular, if \(\omega^{2} \mathrm{LC}=1\), when the inductive and capacitive reactances cancel, comment on what happens.
