Hi,
I am facing an interesting problem.This problem is not about my homework but I got this from a book written on Electrical machines(by B.L.Theraja) .In his book he told that power factor of a three phase induction motor become less than 0.5 when running on light load.But I am thinking about is there any mathematical proof to get the problem solved?I am thinking but could not get hold on it....What I get oppose the problem.I tried to make a relation between voltage and current........I want help
