  1. 2. - switch responds to an external force to mechanically change an electric signal.
  2. 4. - a unit of measure of the rate of electron flow or current in an electrical conductor
  3. 6. circuit - has two or more paths for current to flow through.
  4. 9. - a measurement of resistance between two points of a conductor when a constant potential difference of one volt (V) is applied to those points and a current of one ampere (A) is produced.
  5. 10. - the rate at which heat passes through a specified material, expressed as the amount of heat that flows per unit time through a unit area with a temperature gradient of one degree per unit distance.

  9. 17. - phenomenon associated with stationary or moving electric charges.
  10. 19. constructed models from two materials with different thermal conductivities"
  11. 20. A strip or wire of metal inserted in an electric circuit, which melts (or 'blows') and so interrupts the circuit when the current increases beyond a certain safe strength.
  12. 21. - the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light.
  13. 22. - a measure of the opposition to current flow in an electrical circuit.

  7. 13. circuit - electrically conducting pathway comprising an electric circuit along which the whole current flows through each component.
  8. 16. -the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body.
  9. 18. - a closed loop that electrons can travel in.
