Answer Posted / pravesh
as we know the equation of power in single phase circuit
that if P= VI COS PHI
I IS CONSTANT for rated equipment
POWER IS CONSTANT
SO V= P/(I cos Phi)
as we have inductive load in home so power facter varies
thus voltage is inversely proportional to the power
factor.hence the voltage fluctuates due to variation of
power factor
