a) A variable capacitance and a resistance of 100 2 are connected in series across a 240-V; 50-Hz supply. Draw the complex or locus of impedance and current as the capacitance changes from 4uF to 28 µF. From the diagram, find (a) the capacitance to give a current of 0.6 A and (b) the current when the capacitance is 11 µF. b) A circuit consists of an inductive coil (L = 0.1 H, R = 10 Q) in series with a variable resistor (0 – 250 ). Draw to scale the locus of the current vector when the circuit is connected to 230-V, 50-Hz supply mains and the resistor is varied between 0 and 100 2.
