Items that allow electricity to pass through them are called conductors.

Here are some examples of common conductors:

* Metals: Copper, silver, gold, aluminum, iron, steel

* Water: Especially if it contains impurities like salts or minerals

* Graphite: A form of carbon

* Electrolytes: Solutions that contain ions, like salt water

* Plasma: An ionized gas

* Some semiconductors: Like silicon and germanium, depending on their doping

Why do these materials conduct electricity?

Conductors have free electrons that can move easily throughout the material. When a voltage is applied, these electrons flow, creating an electric current.
