Power source, load, and conductors
Power source, wires, and conductors
Power source, resistors, and conductors
Which type of wiring diagram is appropriate for large or complicated circuits?
layouts
Pictorials
Schematics
Pictograms
In instances where the schematic symbol represents a multi-cell battery, it can mean either multiple cells in a single case or
A single powerful battery
A generator providing DC power
A generator providing AC power
An array of single cell batteries arranged to function like a multi-cell battery
Light emitting diodes are primarily used in weapon system applications as
Current restrictors
Heating elements
Status indicators
Light sources
In 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.
What are the two types of fuses?
Slow-blown
Copper-composite
Oxygen filled
Regular
Circuit 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.
The circuit energizing the relay is called the actuating or primary circuit.
