A circuit is subjected to a sinusoidal AC voltage with a frequency of 600 Hz and a peak voltage of Vp = 100 V. The circuit contains a 200 Ω resistor, a 2.50 µF capacitor, and a 0.875 H capacitor.
(a) What are the maximum and rms current in the circuit?
(b) What is the phase shift between the voltage and the current?
