Ideally, neutral would have same potential as ground, which, when measured against ground is zero. In some electrical panels, grounds and neutrals are not bonded (e.g. not connected electrically), and can have different potentials because of impedance of the difference between the earth and the transformer neutral (center tap) conductor, if there's not a ground rod or bonded, metal water pipe close to the panel.

In the USA, National Electrical Code requires neutral and ground to be bonded except in certain cases. Green-colored insulation is used on ground conductors; white is used for neutral. If there is a fault or a break in the neutral conductor, the ground conductor provides a secondary level of shock hazard protection.

You first typed, "what is the difference b/w neutral and ground".

If you used real words instead of lazy person (b/w) shortcut the question might make sense.

Neutral means having no opinion. Ground is what you walk on.

This is not a forum to educate people in engineering. You have colleges for that. Go there please. If you have already done so, please see this link:google

Sir it is a nice question i also wanted to know that if you believe i was about to ask about it in forum. I think ideal ground is 0ohms but not (5ohms), and neutral is always close to zero ohms but less than that of ground resistance making it to close a network purely. please update if you got the answer and dont end up like this. regards hithu

Are you talking about ground resistance ? that is decided by codes, with voltage and other factors being thrown in.

The ground is theoritically Zero Voltage (or potential), just taken as reference. Any initial textbook on electrical engineering (or even earlier physics where the talk about electircity, capacitance etc) will tell you.

The neutral is the voltage from which the polyphase system potentials are phasor balanced.

for example in simplest (3 phase system) thisis the voltage at from which the three phase voltages are V(0o), V(120o) and V(240o).

From ground these therr voltages ned not be balanced (eg in case unbalanced loads)

There are articles on these topics in Wikipedia.
