Answer / praveen reddy

Earth(North america)and Ground(other countries)is a
conductor provide low impedance path to earth to prevent
high voltages appearing on equipment n doesntcarry current
but neutral used in 2 wire 3 wire systems further connected
to earth,neutral maintains same voltage level to other
conductors and carrys current

Answer / ramesh

Earthing is the path through which the current flows towards
earth in faulty condition to protect the system because in
faulty situation this current
will be several times higher than the normal operation.

Neutral is the return path for the current flows in healthy
operating condition

Grounding are the path for which heavy amount of in crush
current will passes
these referring as two types one is Chassis ground for get
neural connection
other is for faulty condition
