Aircraft Electrical Systems Part 3 Flashcards
The electrical component that controls large amount of current of a starter motor, is called a -
Solenoid
The generator output to a battery when the battery is low, should be -
high
The generator output to a battery when the battery is full, should be -
low
The component that regulates voltage to a battery?
Voltage regulator
The resistance of a copper wire increases as the wire becomes -
hot
Between these factors, which can be used to regulate the output voltage?
- The strength of the magnetic field
- The speed at which the conductors cut the magnetic field
- The number of conductors that cut the magnetic field
The strength of the magnetic field
In the case of DC systems, protection for reverse current is provided in the form of -
reverse current cut-out relay or reverse current circuit breakers
In the case of AC systems, protection for reverse current is provided in the form of -
diodes in the alternator
