For a single-phase circuit served by an AC power source:

(a) Determine the total impedance at 60 Hz of a circuit consisting of a 0.25 H inductor with a 100 Ω resistance and a 50 μF capacitor, all connected in parallel.

(b) If the resistance, inductor, and capacitor are connected to 120 V AC source, determine the magnitude as well as the phase angle (relative to the voltage) of the source current drawn.
