Circuit: The complete path that an electric current follows, including the energy source. A battery is an example of an energy source.
Conductor: A substance that transfers heat, electricity, or sound. Copper wire is an example of a conductor of electricity.
Current: The rate of flow for an electric charge, or how much electricity is flowing. A strong current means that a lot of electricity is flowing.
Electricity: A form of energy caused by the flow of electrons that occurs naturally and can be transferred through conductive materials like wires.
Electrons: Tiny pieces of electricity that are so small, you can’t even see them with the most powerful microscopes. Electrons are part of atoms, and atoms are what everything in the world is made of.
Switch: A small device that starts or stops the flow of electricity when pressed or moved up or down.
