i want to ask that as everybody knows that in star connection on star point is called neutral. my question is that why on that poin called neutral. what is the reason behind it. what is the logic behind it. i heared somewhere that on this point all phases current become zero thats why. if this answer is right then prove why on that point is current become zero. if this answer is not right then tell me the right answer. post ur answer here or on my mail address. m.ikram786@yahoo.com m.ikram555@gmail.com. thanks.
