Problem
A sinusoidal source of rms voltage 220 V, 50 Hz is connected in series with a resistance of 10 Ω, an inductance of 0.10 H and a capacitance of 100 µF.
(i) Find the numerical values of the inductive reactance XL and the capacitive reactance XC at 50 Hz.
(ii) Calculate the magnitude of the impedance Z of the series circuit.
(iii) Hence determine the rms current supplied by the source.
