A series RCL circuit contains only a capacitor (C=7.39 µF), an inductor (L=5.77 mH), and a generator (peak voltage = 78.5 V, frequency - 3.05 x 10³ Hz). When t-Os, 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-8.27 x 10 s. (b) What is the instantaneous value of the current when t-8.27 x 10 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. (a) Number (b) Number i Units Units 0
