  1. 2. - An automatic switch that opens if the current exceeds safe levels.
  2. 6. - A cell with solid or paste electrolytes, like in a flashlight battery.
  3. 7. - A device that converts heat energy into electrical energy.
  4. 12. - A material that allows electric charges to flow easily, like metals.
  5. 14. - An unintended new path of very low resistance.
  6. 15. - The loss of static electricity as charges move off an object.
  7. 17. - A device that converts light energy into electrical energy.
  8. 21. - A common unit used by power companies to measure electrical energy usage.
  9. 22. - An electric charge that builds up on an object.
  10. 23. - The basic unit of matter, made up of protons, neutrons, and electrons.
  11. 24. - A circuit that has more than one path for current to flow.

Down
  1. 1. - Too many devices using power on a single circuit.
  2. 3. - A material that does not allow electric charges to flow easily, like rubber or plastic.
  3. 4. - A complete circuit that allows current to flow.
  4. 5. - A device that transforms electric energy into another form of energy.
  5. 8. - One or more cells connected together.
  6. 9. - The rate at which electric energy is converted into another form. Measured in watts.
  7. 10. - The difference in electric potential between two points in a circuit. Measured in volts.
  8. 11. - A circuit with one path for current to flow through all loads.
  9. 13. - A circuit that has a break so current cannot flow.
  10. 16. - A complete, closed path in which electric current can flow.
  11. 18. - A device that converts chemical energy into electrical energy.
  12. 19. - The rate at which charge flows past a point in an electric circuit. Measured in amperes (amps).
  13. 20. - A property of materials that resists electric current flow. Measured in ohms.
