(b) A star-connected three-phase load absorb 3000 W with power factor 0.433 lagging has a resistance series with an inductance in each branch. It is connected to the 400Vrms (line voltage), 4-wire, 50 Hz, 3-phase supply with the phase sequence is ABC and phase-A as reference has angle 10°. (i) Sketch the circuit diagram of the system. (ii) Calculate the phase voltages of each loads.
