The material that allows electricity to pass through it easily is called a conductor.

Here are some examples of good conductors:

* Metals: Copper, silver, gold, aluminum

* Solutions of salts and acids: These contain ions that can carry electrical charge.

* Plasma: A superheated gas where electrons are stripped from atoms, making it highly conductive.
