electricity - Difference between live and neutral wires


In domestic electrical circuits, there are 3 wires - live, earth and neutral. What is the difference between the live and neutral wires?


As there is AC supply, it means that there are no fixed positive and negative terminals. Current rapidly switches direction. Does that not mean that both the live and neutral wires carry the same amount of current, alternatively? Why is the neutral wire called 'neutral'?
