An inductor (L = 400 mH), a capacitor (C = 4.43 µF), and a resistor (R = 500 Ω) are connected in series. A 50.0-Hz AC generator connected in series to these elements produces a maximum current of 250 mA in the circuit.
(a) Calculate the required maximum voltage ∆Vmax.
(b) Determine the phase angle by which the current leads or lags the applied voltage.
