star to delta or vice varsa network conversion can be achieved by time.
First give the time limit to the timer after that time it will automatically converted to your convenient.

v=I*R, i.e V is directly proportional to I. now P=V*I. so V=P/I. thus v is inversely proportional to I. so what is the correct one? If both are correct than for which kind of condition this 2 differ
