- APrimary circuit
- BActuating circuit
- CSecondary circuit
- DControlled circuit
8Relays are made to operate on a
- ASmall amount of current
- BLarge amount of current
- CSmall amount of voltage
- DLarge amount of resistance
9What restores a reed relay to its de-energized state?
- ASeparate spring
- BRestoring force
- CSpring force in the reed pulls contacts apart
- DSpring force in the reed pulls contacts together

12What three components are found in all circuits?
- APower source, load, and resistors
- BPower source, load, and conductors
- CPower source, wires, and conductors
- DPower source, resistors, and conductors
13Which type of wiring diagram is appropriate for large or complicated circuits?
- Alayouts
- BPictorials
- CSchematics
- DPictograms
14In instances where the schematic symbol represents a multi-cell battery, it can mean either multiple cells in a single case or
- AA single powerful battery
- BA generator providing DC power
- CA generator providing AC power
- DAn array of single cell batteries arranged to function like a multi-cell battery
15Light emitting diodes are primarily used in weapon system applications as
- ACurrent restrictors
- BHeating elements
- CStatus indicators
- 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.
- AVerdadeiro
- BFalso
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.
- AVerdadeiro

19The circuit energizing the relay is called the actuating or primary circuit.
- AVerdadeiro
- BFalso
