A composite load consists of 3 loads connected in parallel.Onedraws 100W at a power factor of .92 lagging, another takes 250W ata PF of .8 lagging, and the third requires 150W at a unity PF.The parallel load is supplied by a source Vs in series with a 10Ωresistor.The loads must all operate at 115Vrms.
Determine a)the rms current through the source; b) the PF of the composite load.
