Answer / abhishek maji

In a single phase system very often three wires are provided: 1.LIVE,2.NEUTRAL,3.EARTH.In the single phase system we have to prove a return path for current otherwise no current will flow...and that is the typical job done by the neutral wire i.e. it serves as a return path...On the other hand earth is provided for the purpose of protection,whenever a fault occurs in the system huge fault current which is many times the rated current flows through the earth wire and in thus way protects the system...

In AC if the direction of current keeps reversing every half cycle, how does it propogate through the transmission lines?
