3 Two impedances z1 and z2 when connected separately across a 230V 50Hz supply consumed 100W and 60W at power factor of 0.5 lagging and 0.6 leading respectively. If these impedances are now connected in series across the same supply, find a) total power absorbed and overall p.f. b) the value of the impedances to be added in series so as to raise the overall p.f. to unity, c) draw the circuit and diagram/s.
