An AC source operating at 60. Hz with a maximum voltage of170 V is connected in series with a resistor (R = 1.2 kΩ) anda capacitor (C 5 2.5 µF). (a) What is the maximum value ofthe current in the circuit? (b) What are the maximum valuesof the potential difference across the resistor and the capacitor?(c) When the current is zero, what are the magnitudesof the potential difference across the resistor, the capacitor,and the AC source? How much charge is on the capacitor atthis instant? (d) When the current is at a maximum, what arethe magnitudes of the potential differences across the resistor,the capacitor, and the AC source? How much charge is on thecapacitor at this instant?
