Electricity

7. A material (usually metal) that allows electricity to flow easily.
8. A device that opens or closes a circuit, controlling the flow of electricity.
11. Energy Heat energy produced when electricity flows through materials with resistance.
12. Tiny negatively charged particles that move to create an electric current.
14. A device used to measure the amount of current flowing in a circuit.
16. A power source that uses chemical reactions to produce an electric current.
17. The rate at which electrical energy is used or changed into another form (measured in watts).
18. Circuit A circuit that has multiple paths for electricity to flow.
19. Energy Stored energy in a battery that is released as electrical energy.

1. A closed loop or complete pathway that allows electrical energy to flow.
2. A component that slows down or opposes the flow of electrical current.
3. A metal that is an excellent conductor, commonly used in electrical wiring.
4. The energy or “push” that moves charged particles through a circuit.
5. The flow of charged particles (electrons) past a point in a circuit each second.
6. A material that blocks the flow of electricity and helps keep people safe.
9. The ability to do work; it can be transferred or transformed but not created or destroyed.
10. Circuit A circuit where components are connected in a single path, one after another.
13. A material used as an insulator to safely cover wires.
15. Energy The energy of motion, such as when electricity powers a fan or motor.
20. A device (like a light bulb or motor) that uses electrical energy to do work.
