Down
  1. 1. when the path along which electric charges normally flow is not complete
  2. 3. energy caused by the movement of electrical charges
  3. 5. material used to reduce or prevent the transfer of electricity, heat, or sound
  4. 6. path that forms a complete loop along which electrical charges can flow
  5. 9. stored energy that an object has because of its position or condition
  6. 11. when energy moves from one place or object to another
  7. 13. material that readily allows electric charges to pass through it and therefore carries electricity well
  8. 14. energy stored in matter and released during a chemical reaction
  9. 16. to transmit heat or electricity through a material or substance
  10. 21. to take in energy
