Q4. A balanced three phase delta connected load comprises a coil of resistance 50Ω and inductance 0.1 H in each phase. It is connected to a 440 V 50 Hz supply.  Calculate EACH of the following: (a) The line current for the load; (b) The power factor of the load; (c) The power dissipated by the load; (d) The component values in each leg of a star connected load which would draw the same line current at a leading power factor numerically equal to that found in Q4(b).
