Answer / sri

Neutral is used to make the circuit complete.

Earth is used to protect the instuments or whatever ,from
electrical shock.

Ground is used to bypass the electrical leakages

Answer / sushil

neutral is a return path for current,
earth is the terminal connected to an earthing pit provided
for protection purpose and
ground is a referance terminal at 0 volt used for general
purposes such as testing, return path. It may or may not
connected to the earthing pit, it may be connected to the
body of equipment, base plate, etc

Answer / nvs sankaram

Neutral and Erath both will connected to Earth pit thorugh
Earth Electrode Ground is nothing but a circuit collective
or distributive point where zero potential will be made(as
per Kirchoff's law).

Answer / ashiah

Earthing is done for body of equipment to protect elctric
shok & Neutral means connect the winding of equipment from
