A resistor (R = 900 ?), a capacitor (C = 0.25 µF), and an inductor (L = 2.0 H) are connected in series across a 240 Hz AC source for which ?Vmax = 125 V. Calculate the following.
(a) the impedance of the circuit
?
(b) the maximum current delivered by the source
A
(c) the phase angle between the current and voltage
