What are some examples of insulators and conductors?

As regards electrical conductors, these materials have free electrons that will support electric current flow. In general, all metals will conduct electricity, though some do it better than others. We know that silver, copper, gold and aluminum top the list of metals that have high electrical conductivity.

Insulators don't have free electrons to support electric current flow. These materials include rubber, dry wood and dry paper, many plastics, glass, ceramics and many other materials.Boobaa
