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