An AC sine wave voltage of 100V, 60Hz is applied to a circuit consisting of a resistor
(R = 120 ), coil (L = 4 H), and capacitor (C = 3 x 10
-6
F) connected in series.
(1) Find the impedance of the circuit.
(2) Find the phase difference between the current and the voltage.
Circuit impedance = Value of polar coordinate r
