A balanced inductive load, connected in star across 415-V,50-Hz, three-phase mains, takes a line
current of 25A. The phase sequence is RYB. A single-phase wattmeter has its current coil connected in the R
line and its voltage coil across the line YB. With these connections, the reading is 8 kW. Draw the vector
diagram and find (i) the kW (ii) the kVAR (iii) the kVA and (iv) the power factor of the load
