A series RCL circuit contains only a capacitor (C=6.60 �F),
an inductor (L=7.20 mH), and a generator (peak voltage=32.0 V,
frequency=1.50x10^3 Hz). When t � 0 s, the instantaneous value of
the voltage is zero, and it rises to a maximum one-quarter of a period
later. (a) Find the instantaneous value of the voltage across the capacitor/
inductor combination when t=1.20x10^-�4 s. (b) What is the
instantaneous value of the current when t=1.20x10^-�4 s? (Hint:
The instantaneous values of the voltage and current are, respectively, the
vertical components of the voltage and current phasors.)
