Problem
A 50Ω resistor, a 120mH inductor and a 50μF capacitor are connected in series to a 200Vrms,50Hz AC source.
(a) Sketch a labelled phasor diagram taking the circuit current as the reference.
(b) From the diagram, calculate the phase angle between the supply voltage and the current (nearest degree).
