An inductor (L = 400 mH), a capacitor (C = 4.43F), and a resistor (R = 500

Question:

An inductor (L = 400 mH), a capacitor (C = 4.43μF), and a resistor (R = 500Ω 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.
