Question
A series RCL circuit contains only a capacitor (C =
6.98 µF), an inductor (L = 5.87 mH), and a generator
(peak voltage = 84.8 V, frequency = 5.00 x 103 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 = 9.35 x 10-4 s. (b) What is the instantaneous
value of the current when t = 9.35 x 10-4 s? Be sure
to include the plus and minus signs in the answers if
applicable. (Hint: The instantaneous values of the
voltage and current are the vertical components of the
voltage and current phasors, respectively.) Note: The ac
current and voltage are rms values and power is an
average value unless indicated otherwise.
