Across
  1. 1. a circuit with multiple paths for electrons to flow
  2. 4. there are many forms like kinetic, mechanical, electrical, thermal. measured in J
  3. 5. a cell that cannot be recharged
  4. 8. a device that converts electrical to mechanical
  5. 10. A buildup of charge, like when your hair stands on end.
  6. 11. a cell that can be recharged
  7. 12. uses a paste as an electrolyte
  8. 19. measured in the unit of ohms
  9. 20. the measure of the force behind each electron. Like the height of a waterfall
  10. 24. a safety devices that prevents too much current from flowing but can be easily reset.
  11. 25. The amount of electron flow
  12. 26. a resource that will not comeback once used up like coal or radioactive fuel
Down
  1. 2. the solid material, usually metals that make up the positive and negative side of a cell
  2. 3. an unintended pathway for electrons
  3. 6. that rate at which a device uses energy
  4. 7. uses a liquid electrolyte
  5. 9. a device that converts thermal to electrical energy
  6. 13. a device that helps reduce the flow of electrons
  7. 14. the conductive liquid in a cell
  8. 15. When the built up charges suddenly move. like a lightning bolt.
  9. 16. a complete pathway for electrons to flow
  10. 17. a device that stops the flow of current by physically breaking the connections
  11. 18. a material that allows electrons to flow easily
  12. 19. a resource that will continually regenerate or come back. Like wind or solar energy.
  13. 21. a material that prevents the flow of most electrons
  14. 22. a circuit with a single pathway for electrons to flow
  15. 23. a device that converts mechanical to electrical energy
