Across
  1. 3. - unit used to measure a material’s resistance
  2. 6. (R) - tendency of a material to prevent electrical flow
  3. 10. current (AC) - electricity flow changes direction with armature(turning magnet) change
  4. 11. circuit - current cannot flow through
  5. 14. Law - flow of electricity through a conductor is directly proportional to the electrical force that produces it (R = E/I)
  6. 15. wire - carries current away from appliance and back to source
  7. 16. - source of electricity connected to a light, heater, or motor
  8. 17. - form of energy that can produce light, heat, magnetism, and chemical changes
Down
  1. 1. - measure of the amount of energy or work that can be done by amps and volts (volts x amps)
  2. 2. - measure of the rate of flow
  3. 4. wire - carries current
  4. 5. - an additional connection between equipment and the earth
  5. 7. - material that provides great resistance to electricity flow
  6. 8. current (DC) - electricity flows in one direction
  7. 9. - tubing that contains individual insulated wires
  8. 12. circuit - occurs when resistance is not high enough for flow of electricity; flows through circuit and back to source too quickly
  9. 13. (E) - measure of electrical pressure
  10. 16. - a material that electricity flows freely through
