FAA regulated questions..

• Some electric motors have 2 sets of field windings wound in opposite directions so that the--Motor can be operated in either direction.
•  One purpose of growler test is to determine the presence of-- A shorted armature.
• Electric wire terminals for most aircraft applications must be what type?-- Ring type.
• Principle advantage of the Series wound DC motor--- High Starting Torque.
• If a generator is equipped with a vibrator-type voltage regulator, the actual time the voltage regulator points remains open---Depends on the load carried by the generator.
• What is the cause of generator brush arcing?-- Low Spring Tension.
• When AC generators are operated in parallel, the--- Frequency and Voltage must be equal.
• The starting current of a series-wound DC motor, in passing through both the field and armature windings produces a--- High Starting Torque.
• Which motor would bee most likely to have an armature brake?-- Landing light Retraction Motor.
• The method most often used in overcoming the effect of armature reaction is through the use of--Interpoles.
• The only practical method of maintaining a constant voltage output from an aircraft generator under varying conditions of speed and load is to vary the-- Strength of the magnetic field.
• The pole pieces or shoes used in a DC generator are a part of the-- Field assembly.
• How many cycles of AC voltage are produced in a six-pole alternator of the revolving-field type for each revolution of the rotor?-- Three
• If the reverse current cut-out relay( RCCR) contact points fall to open after the generator output has dropped below battery potential, current will flow through the generator armature-- Opposite the normal direction and through the shunt field in the normal direction.
• How does the magnetic brake used to stop rotation of an electric motor armature operate?-- A friction brake is applied by a spring and released by a magnet.
• In a generator, what eliminates any possible sparking to the brush guides caused by the movement of the brushes within the holder?-- The Brush Pigtail.
• A series-wound DC electric motor will normally require--More current at low RPM than at high RPM.
• Aluminium wire must be stripped very carefully because-- Individual strands will break easily after being nicked.
• The commutator of a generator-- Changes AC produced in the armature into DC as it taken from the armature.
• An ammeter in a battery charging system is for the purpose of indicating the-- Rate of current used to charge the battery.
• Not the purpose of interpoles in a generator----- Reduce Field Strength.
