Electrical

3. movement of tiny particles called electrons
6. commonly called BX
7. current can take one of two or more paths to return to source
8. detects very small current flowing from the live conductor to ground
9. point in the system where equipment can be plugged in or permanently wired
10. large switch that allows all electric power to the building to be disconnected
11. automatic switch which opens the circuit if an excess of current tries to flow
12. current is allowed to flow back to the source without overcoming the resistance of the device
14. force that slows the flow of electric current
16. amount of current flowing through a device
17. force that causes the current to flow

1. current does not return to the source
2. commonly called romex
4. devices are wired in line with one another so current must flow through each device to return to source
5. metal or plastic tubing with conductors running inside it
13. electrical work is measured in units called
15. arrangement of materials that allows current to flow
