(a) Define: (i) reactance; (ii) impedance.

(b)(i) Explain resonant frequency of an RLC circuit.

(ii) Explain the statement — the power supply voltage of a source is 230V

(c) A source of e.m.f 240V and frequency 50 Hz is connected to a series arrangement of a resistor, an inductor and a capacitor. When the current in the capacitor is 10A, the potential difference across the resistor is 140 V and that across the inductor is 50 V. Calculate the:

(i) potential difference across the capacitor (ii) capacitance of the capacitor; (iii) inductance of the indicator.

(d) Draw and label one vector diagram for the potential differences across the inductor, the capacitor and the resistor in (c) above.
