  1. 3. A component that can safely open or close a circuit to turn a device on or off
  2. 5. The term used to describe a complete, unbroken loop through which electric current is able to flow
  3. 6. An instrument connected in series to measure the rate of flow of electric charge
  4. 8. A component designed to oppose, reduce, or limit the size of the current in a circuit
  5. 11. A type of circuit that has only one single loop or path for the electric current to flow
  6. 12. A fundamental property of matter that can be either positive or negative
  7. 13. The standard SI unit used to measure electric current
  8. 14. The standard SI unit used to measure voltage or potential difference
  9. 15. A single, separate path or loop inside a parallel circuit system
  10. 17. The standard scientific unit used to measure the quantity of electric charge
  11. 18. Two or more electrical cells connected together in series to provide more energy
  12. 19. The scientific term for the flow of electric charge around a complete circuit
Down
  1. 1. The negatively charged particles that flow through a metal wire to form an electric current
  2. 2. Because like charges repel and opposites attract, electrons in a circuit always flow toward this terminal of a cell
  3. 4. An instrument connected in parallel to measure the potential difference across a component
  4. 7. A circuit that contains more than one path or loop for the current to split down
  5. 9. A material, such as plastic or glass, that does not allow electric current to flow through it easily
  6. 10. A measure of the energy given to the charge carriers in a circuit, also known as potential difference
  7. 12. A single component that provides electrical energy to push charge around a circuit
  8. 16. A material, usually a metal like copper, that allows electric current to flow through it easily
