Electrical Theory

3. carries current to appliance
5. measure of the rate of flow
6. measure of the amount of energy or work that can be done by amps and volts (volts x amps)
9. measure of electrical pressure
10. source of electricity connected to a light, heater, or motor
11. tendency of a material to prevent electrical flow
13. carries current away from appliance and back to source
14. form of energy that can produce light, heat, magnetism, and chemical changes
15. an additional connection between equipment and the earth
16. current cannot flow through
17. material that provides great resistance to electricity flow

1. electricity flow changes direction with armature(turning magnet)change
2. electricity flows in one direction
4. occurs when resistance is not high enough for flow of electricity; flows through circuit and back to source too quickly
7. tubing that contains individual insulated wires
8. flow of electricity through a conductor is directly proportional to the electrical force that produces it (R = E/I)
12. a material that electricity flows freely through
