Across
  1. 5. circuit An electric circuit in which electrons can flow from one pole of the power source to the other in a continuous path.
  2. 6. The rate at which electrons flow through a wire in a given period
  3. 8. The current used in batteries, which flows in one direction.
  4. 11. electricity The flow of electrons
  5. 12. code A series of 1s and 0s.
  6. 13. A material that resists or blocks the flow of electrons
  7. 16. Materials that conduct electricity without any loss of energy due to resistance.
  8. 17. An electric circuit that is broken into several branches so the current flows into multiple paths.
  9. 23. A solid or a liquid solution that contains ions from chemical reactions occurring at the electrodes in a battery.
  10. 24. A semiconductor device with two electrodes that only lets current flow in one direction
  11. 25. Solid elements, such as silicon or germanium, that have electrical conductivity between that of a conductor and an insulator.
  12. 27. A battery that contains a liquid electrolyte, which is free to flow and move.
  13. 28. The pressure of an electric current.
  14. 29. A current that changes direction because it is produced at a power station using a rotating current generator.
  15. 30. A portable source of electrical energy stored in chemical form containing two or more cells
  16. 31. The sudden release of static electricity between two differently charged objects.
  17. 32. When a material resists the flow of electrons.
Down
  1. 1. Special switches that are designed to open when too much current passes through them.
  2. 2. An electric circuit with an open switch so there is a break in the circuit and electrons cannot flow.
  3. 3. The part of the electric pathway in an electric circuit that uses current, such as a bulb or motor.
  4. 4. An electric circuit where the current flows in a single path.
  5. 5. A material that allows electrons to move freely from atom to atom in a continuous path.
  6. 7. A device that converts chemical energy to electrical energy. The working part of a battery.
  7. 9. A small sandwich of two different types of semiconductors.
  8. 10. Tiny electric circuits printed on thin chips of silicon.
  9. 14. Terminals that conduct electricity.
  10. 15. A device that limits the amount of electrical current flowing through a circuit.
  11. 18. The unit for measuring the flow of electric current
  12. 19. A natural electrostatic discharge that occurs because of a difference in charge between a cloud and the ground.
  13. 20. A battery that uses a combination of thick, paste-like chemical for the electrolyte.
  14. 21. Batteries that can be used repeatedly.
  15. 22. A material’s ability to allow electrons to flow.
  16. 26. Devices, such as televisions, radios, and computers, that operate using small electrical parts and the flow of electrons.
