Question:

A resistor (R = 900 Ω), a capacitor (C = 0.25 µF), and an inductor (L = 2.5 H) are connected in series across a 240-Hz AC source for which ∆Vmax = 140 V. Calculate
(a) The impedance of the circuit,
(b) The maximum current delivered by the source, and
(c) The phase angle between the current and voltage.
(d) Is the current leading or lagging the voltage?
