Ground or earth in a mains (AC power) electrical wiring
system is a conductor that provides a low impedance path to
the earth to prevent hazardous voltages from appearing on
equipment (the terms "ground" (North American practice)
and "earth" (most other English-speaking countries) are
used synonymously here). Normally a grounding conductor
does not carry current. Neutral is a circuit conductor that
may carry current in normal operation, and which is usually
connected to earth.

Answer / kuldeep

earth is a protective path but neutral is a return path
for electron
