As what I learn, used electricity is disposed away through neutral wire, but where the neutral wire go? Is it goes into earth? Then its function should be same with the earth wire, isn't it?

These answers are mostly garbage, though there is some correct stuff mixed in if you already know how it works. So it's a good example of why you should not use Yahoo!Answers to try to learn about something serious.
Try an internet search on "electrical distribution system" or "house wiring." You will find correct information, along with pictures and diagrams.
Good luck.

With Alternating Current (VAC), there is a push-pull function from the dynamo which requires both wires to be connected.
The issue is that there has got to be a means to 'float' the environment around the electrical device you are using, called 'ground' or 'neutral'. Though it provides no direct activity in the usage of the electricity, it has become a safety feature.
In the old days, there were only two wires. The 'return' wire to the dynamo was connected to the chassis of the appliance. We decided that if the return wire was isolated from the chassis, then the safety factor increased. Thus, we got 'three-wire' systems.
The neutral wire is now connected to a stake driven into the ground outside your home. This 'grounding stake' permits the electrical system of your house to exactly match the local environment, which means that if your appliance has a problem, then you can touch its casing and most probably not be shocked. That is why it is called 'neutral'.

In an AC circuit, the neutral wire complete the electrical path back to the power source. Ultimately, this is a generator set. The ground wire goes to earth and is different than the neutral. The function of the ground is for safety. It keeps the electrical potential of any equipment at zero to prevent shock hazard.

On some systems the neutral is only connected to earth at the substation, so there could be a couple of volts between house neutral and house earth.

i in my opinion think of you greater constructive hire an electrician earlier you the two a) Burn your place down or b) Kill your self. You for sure have not any clue what you're doing and could desire to place the disguise on the breaker container and walk away.
