What follows is a plain HTML version of the Quiz.
All of the questions and answers in this quiz are found in Tom Henry's book, "The Electrician's Workbook".
1. Voltage drop times amperage equals power (watts) loss.
2. The length of time that a fault current would flow on the equipment grounding conductor would be approximately
.
- [ ] 1/2 cycle
- [ ] 60 cycles
- [ ] 6 seconds
- [ ] 120 cycles
3. A conductor carrying current encounters heat from two sources, the heat that is generated in the conductor from the flow of current and the heat from .
- [ ] the capacitance of the conductor
- [ ] the inductance of the conductor
- [ ] the ambient temperature
- [ ] the resistance of the conductor
4. Which of the following is a false statement?
- [ ] A continuity test can be performed on a fuse
- [ ] If a fuse clip or fuseholder of the proper size is not available, bend the clip to the size needed
- [ ] The most common cause of excessive heat in electrical equipment is loose connections.
- [ ] A circuit breaker should be operated manually by operating the handle periodically to keep the mechanism free and the contacts clean
5. The ampacity of a conductor is defined as the current in amperes that a conductor can carry continuously under the conditions of use without exceeding its rating.
- [ ] temperature
- [ ] voltage
- [ ] amp
- [ ] resistance
6. A 20 amp receptacle can be rated 75  C even though it is 100 amps or less.
7. A leakage of current to ground, caused by worn, frayed or defective insulation, moisture or tools that have deteriorated with abuse or age is known as a .
- [ ] leaking wire
- [ ] short circuit
- [ ] leaking circuit
- [ ] ground fault
8. A #12 conductor with 75  C insulation can withstand 25 amps.
9. As long as the apparent let-thru current of the fuse is more than the interrupting rating of the breaker, the fuse offers protection.
10. The circuit breaker has a bimetallic element that trips on the amount of heat.
