							Free electrons are also known as conduction electrons. Each copper atom provides a single free electron, so there are as many free electrons as atoms. When a voltageis connected across a piece of copper, it pushes the free electrons so that they flowthrough the metal – that's an electric current

More precisely, the flow of electrons is an electric current. Protons do not flow in an electric circuit; they stay fixed in place because they’re much heavier than the electrons. However, protons can flow in a plasma. In that case, the flow of protons is also called an “electric current.”

By convention, the direction of flow of electric current is opposite the direction of electron flow. In a plasma, if protons are moving, the resulting current is in the same direction as proton flow.
