AC Current Direction in Earth Wire
We have studied about AC that it changes its direction. That is why we do not use polarity sign in AC.But in some books a + sign is used with AC source.
My first question is if current changes it direction then both wire will work the same. Then why do we use term Live & Neutral wire.
Secondly, if we connect the neutral wire to earth the current will flow.The question arise here, AC changes it direction but how will current change its direction connected to earth because only Phase wire is connected to AC source. I mean the earth serve as sink.
