In three phase power flow, the equation P = \(\sqrt3\)VLILcos θ suggests _______ Correct Answer three phase balanced load

In three phase power flow, the equation P = \(\sqrt3\)VLILcos θ suggests three phase balanced load because in unbalanced condition of power flow, this equation does not hold good. In case of balanced loads, the phase currents or voltages are equal and displaced by exactly 120°, exhibiting only positive-sequence components. On the contrary, in case of unbalanced loads, a current or voltage unbalance between phases in magnitude or phase angle generally gives rise to negative and zero-sequence components.

Election for a constituency was conducted in two phases where three contestants A, B and C contested. In first phase 48% of the total voters voted out which A and B got 32% and 46% of the votes (remaining to C). In the next phase where 75% of the remaining people voted A and B got 43% and 33% of the votes casted (Remaining to C). If the amount of votes obtained by A in phase 1 is less than the total votes obtained by B in phase 1 and C in phase 2 by 16080, then what is the total number of voters in the constituency?
