The neutral is created by the transformer connection i.e Delta to Y this has no voltage level.This is used to complete the current path.
While ground also has 0V but this is used for the safety while high current passes.
Usually these two are short circuited together.

Answer / guna

neutral is acts as a closed path for the electric circuit for continuity. residual current will flows through the neutral wire..
Earth wire transfers the high fault currents to the earth. to save the equipment.

Answer / varaprasad inavilli

Current will pass to the circuit when there is a closed path in the circuit.

To creat closed path with phase , we will use neutral in single phase circuits.



Earth:-

it is used to earth the metallic parts to avoid shocks

Answer / vck

Neutral is operating 0potential ckt
Then earth is hazard high current absorbing safety ckt
