Answer Posted / ashish rai
First of all of you notice that p=vi* cos(phi)
Another thing is that for running ac system 10% of voltage
fluctuation is allowed from electricity board.
Hence V is nearly constant factor.
I*cos(phi) is the variable factor hence with variation in
current power factor of system will change not voltage.
If any body is making wrong it plz clarify it.
