Here's why:

* Electric current is the flow of electric charge.

* Conductors allow this flow of charge easily. This is because they have free electrons that can move easily throughout the material.

Examples of conductors include:

* Metals: Copper, silver, gold, aluminum, etc.

* Electrolytes: Solutions containing ions (e.g., salt water)

* Plasma: Ionized gas
