b) The load connected to a three-phase supply comprises threesimilar coils connected in star. If the phase currents are 10A andthe total active power and power factor absorb by the loads are 3kWand 0.8 lagging, respectively. Find:
i. The magnitude of phase and line voltages
ii. Total apparent power (1 mark)
iii. The impedance of each coil.
c) If the coil in Q3(b) are now connected in delta to the samethree-phase supply, calculate the magnitude of the line currentsand the magnitude of the total apparent power.
