Q. Three loads are connected in parallel and fed from a line having a series impedance of 0.1+j 0.5 2 as shown in fig. (1). Load 1 absorbs 20 kW and 8 kVAR Load 2 absorbs 5 kVA at 0.96 p.f leading. Load 3 absorbs 21.4 Kw at unity (1) p.f. Calculate: a) The source voltage Vs. b) The real and reactive power lost in the line. c) The complex power and p.f of the source. d) The combined power factor of the loads.
