- DLight sources
16In a rotary switch, there is a single contact usually located in the center that is surrounded by a series of contacts arranged around the outside.
- ATrue
- BFalse
17What are the two types of fuses?
- ASlow-blown
- BCopper-composite
- COxygen filled
- DRegular
18Circuit breakers are used more extensively today than fuses, since they can easily reset an indefinite number of times, which eliminates the need for replacement as in the case of fuses.
- ATrue
- BFalse
19The circuit energizing the relay is called the actuating or primary circuit.
- ATrue
- BFalse
