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