What is the difference between 3 core and 4 core cable?
What are some distinguishing features between a 3 core and a 4 core electrical cable? A three-core cable comprises live, neutral, and earth conductors. On the other hand, a 4 core power cable consists of one neutral conductor and the remaining three conductors potentially being live wires.
What is wire and types of wire?
The terms wire and cable are often used as synonyms, but they actually have two different meanings. A wire is a single flexible strand of metal.

What are the different types of copper wires in cable?
Copper wires in a cable may be bare, or they may be plated with a thin layer of another metal, most often tin but sometimes gold, silver or some other material. Tin, gold, and silver are much less prone to oxidation than copper, which may lengthen wire life, and makes soldering easier. Tinning is also used to provide lubrication between strands.
