A series AC circuit contains a resistor, an inductor of 240 mH, a capacitor of 4.80 µF, and a source with ?Vmax = 240 V operating at 50.0 Hz. The maximum current in the circuit is 120 mA.
(a) Calculate the inductive reactance.
(b) Calculate the capacitive reactance.
(c) Calculate the impedance.
(d) Calculate the resistance in the circuit.
(e) Calculate the phase angle between the current and the source voltage.
