Q 1: Answer a or b:- a) A variable capacitance and a resistance of 160 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 2) in series with a variable resistor (0 210 2 ). 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.
