We say that if voltage in a power system is increased,for a constant power the current will decrease (by P=VI). isn't this in disagreement with the ohms law(I propotional V;resistant const.).Since the resistance of transmission lines remains constant,shouldn't inc in voltage cause inc in current across the transmission line? I have read many articles across the net but still couldn't this figure this out. :( Guyz plz assist me with dis..:)..
