When the three identical star-connected coils are
supplied with 400 V, 50 Hz, 3- supply, the 1- p
wattmeter whose current coil is connected in line R
and pressure coil across the phase R and neutral
reads 8 kW and the ammeter connected in R-
phase reads 36 Amp. Assuming RYB phase
sequence find: (i) the power factor, of the load , (ii)
