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