 What is live wire and neutral wire?

Ravi Ranjan Accepted Answer Pending Moderation

In our homes, we receive supply of electric power through a main supply (also called mains), either supported through overhead electric poles or by underground cables. The wire usually with red insulation cover, is called live wire (or positive).The wire, with black insulation, is called neutral wire (or negative).
