1. A load of 2.5kW takes a current of 12 Amp from a 230 Volt supply. Calculate the power factor.


2. Three single phase loads are to be connected to a three phase supply. All at unity power factor. The loads are,


i, 60 Amp.


ii, 50 Amp.


iii, 40 Amp.


By any method determine the neutral current.

    Sorry Mike only 8/10.  225 + 75 = 300.  SQRT(300) = 17.32A.


    Now for your homework - calculate the phase to neutral voltages and the voltage between your neutral terminal and the the star point of the supply transformer ?
