ASA ELECTICAL SYS ACTUAL EXAM
GRADED A+
QUESTION6 (8808) - What is a cause of generator brush arcing? - answer-C- Low spring tension.
QUESTION7 (8809) - What is required when operating two aircraft ac generators in parallel? - answer-B-
Frequency and voltage must both be equal.
QUESTION8 (8810) - The starting current of a series-wound dc motor, in passing through both the field and
armature windings, produces a - answer-C- high starting torque.
1 (8803) - Some electric motors have two sets of field windings wound in opposite directions so that the -
answer-C- motor can be operated in either direction.
QUESTION2 (8804) - One purpose of a growler test is to determine the presence of - answer-C- a shorted
armature.
QUESTION3 (8805) - Electric wire terminals for most aircraft applications must be what type? - answer-C-
Ring.
QUESTION4 (8806) - What is the principal advantage of the series-wound dc motor? - answer-A- High
starting torque.
QUESTION5 (8807) - If a generator is equipped with a vibrator-type voltage regulator, the actual time the
voltage regulator points remain open - answer-A- depends on the load carried by the generator.
, QUESTION9 (8811) - Which motor would be most likely to have an armature brake? - answer-B- Landing
light retraction motor.
QUESTION16 (8818) - In a generator, what eliminates any possible sparking to the brush guides caused
by the movement of the brushes within the holder? - answer-A- The brush pigtail.
QUESTION17 (8819) - A series-wound dc electric motor will normally require - answer-C- more current at
low RPM than at high RPM.
QUESTION18 (8820) - The type of electric wire terminals used for most aircraft applications, in addition to
providing good current carrying capabilities, are designed primarily - answer-A- to prevent circuit failure due
to terminal disconnection.
QUESTION19 (8821) - Aluminum wire must be stripped very carefully because - answer-C- individual
strands will break easily after being nicked.
QUESTION20 (8822) - The commutator of a generator - answer-B- changes alternating current produced in
the armature into direct current as it is taken from the armature.
QUESTION21 (8823) - An ammeter in a battery charging system is for the purpose of indicating the -
answer-C- rate of current used to charge the battery.
QUESTION22 (8824) - Which of the following is not one of the purposes of interpoles in a generator? -
answer-A- Reduce field strength.
QUESTION23 (8825) - To test generator or motor armature windings for opens, - answer-A- place
armature in a growler and connect a 110V test light on adjacent segments; light should light.
QUESTION24 (8826) - What is the color and orientation of the position lights for navigation on civil
airplanes? - answer-B- Left side - red, right side - green, rear aft - white.
