Problem
A resistor of 40Ω is connected in series with a 0.20H inductor across a 220V (rms), 50Hz mains supply. Answer the following:
(i) Calculate the inductive reactance.
(ii) Determine the impedance of the circuit.
(iii) Find the rms current drawn from the supply.
(iv) Evaluate the phase angle between the supply voltage and current, and state the nature of the power factor (leading or lagging).
(v) Calculate the average power consumed by the circuit.
