Question 2
A resistor of 15 Ω, an inductor of 0.318 H and a capacitor of 150µF are connected in series across a 240 V, 50 Hz a.c. supply. Calculate the:
- impedance of the circuit;
- current;
- voltage across each component.
Observation
The expected responses were:
Many of the candidates who attempted this question did not know how to compute reactance from capacitance and reactance without which impedance, current and voltage cannot be computed.
