A 77.0-? resistor is connected in series with a 32.0-µF capacitor and a source whose maximum voltage is 123 V, operating at 60.0 Hz.
(a) Find the capacitive reactance of the circuit.
(b) Find the impedance of the circuit.
(c) Find the maximum current in the circuit.
(d) Does the voltage lead or lag the current?
(e) How will adding an inductor in series with the existing resistor and capacitor affect the current? Explain.
