GND vs Neutral
ground and neutral is same in terms of circuitary, but the most popular name given to neutral is ground, represented as GND, other is called Power, represented as PWR.
GND is basically a reference point, the flow of currrent needs circuit completion, so current moves from power to ground.
but the thing most people confuse is
reference ground
and protective ground
refrence ground is what we say GND in circuits,
protective ground is used to make devices,and other things ground to protect them from lightning. like we do in electric poles and telecom towers, usually computer and refrigerators are also grounded for lightning protection.
