Electrical Terms

2. Unit that indicates frequency
4. Safety device used to limit the maximum rate of current flow in a circuit
6. Unit of measure of electrical pressure - force which causes electricity to move through a conductor
8. Material that readily permits electric current to flow through it
11. The ability to do work
13. Electrical circuit which has two or more paths for current to flow (receptacles & lights) - if one becomes defective the circuit will not be broken
14. Hour Unit of measure for determining power consumption on an hourly basis
16. The property of being positive or negative
19. Safety device used to limit maximum rate of current flow in a circuit - when excessive it generates heat which melts this device and opens the circuit
21. Unit of measure of electrical resistance or electrical friction
22. An electrical circuit which has only one electrical path to and from the source (fuses, switches, circuit breakers)

1. Power Rate of producing or using electric energy
3. The movement of electrons through a conductor
5. A single instrument which combines the functions of a voltmeter, ammeter, and ohmmeter
7. Unit of measurement of doing work, generally used to describe the output of electric motors
9. Type of electricity in which electrons flow in one direction only
10. Complete electrical path through which electricity may flow
12. Unit of measure of electrical power
15. Unit of measure of the rate at which electricity passes through a conductor - maximum safe limits of a device
17. Electricity in which the direction of electron flow is reversed at regular interval
18. Material which strongly resists electric current; blocks the flow of electrons
20. Circuit Condition that provides undesired path for electrical current
21. Circuit Condition that provides no path for electrical current
