WHAT IS CONDUCTOR

 

In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge in one or more directions. Materials made of metal are common electrical conductors.

The flow of electricity through conductors is similar to water flowing through pipes and fittings. When electrons flow freely through a material, we say that there is “little resistance” and the material is called a conductor. Copper and aluminum are typical conductors used in electrical wires of varying diameter. In the same way that a fire hose carries more water than a garden hose, a larger-diameter electrical wire allows more electrons to flow than a smaller one. A bigger diameter thus allows more current (higher amperage).
