A shorted circuit may eventually produce an _ by blowing (opening) the fuse , burning out a circuit component , or tripping the circuit breaker

open circuit

4
New cards

_ is the process of locating causes of malfunctions or troubles in a circuit

troubleshooting

5
New cards

AC motors have a number of advantages over DC motors , the main ones being less arcing at____ , _______ , and ___

higher altitude , smaller size , lighter weight

6
New cards

Induction motors have a rotor that is called the ___

Squirrel cage

7
New cards

The synchronous speed of an induction motor is the speed at which the magnetic field rotates, and it depends upon the number of for which the stator is wound _____and the __ of the applied voltage

poles , frequency

8
New cards

The _ of the volt meter is so high that only small current flow is in the circuit

resistance

9
New cards

Troubleshooting a parallel DC circuit for a shorted component should be accomplished with an ___

ohmeter

10
New cards

A short in the series part of a series parallel circuit will cause a ___ in total resistance which will cause total current to __

decrease, increase

11
New cards

The most commonly used reversible type motor in aircraft is

reversible series

12
New cards

To reverse the direction of rotation in a DC motor

Reverse the direction of current in the armature windings or the field windings

13
New cards

A cumulative compound motor has both a series field and a shunt field. The purpose of the shunt field is to

Prevent the motor from running away under a no-load condition

14
New cards

Looking at figure 7-19-19, which of the following statements is true?

R2 becoming short-circuited would cause the fuse to blow

15
New cards

For all induction motors , the principle of operation is a

Rotating magnetic field

16
New cards

The squirrel cage rotor in an induction motor has a speed of rotation determined by

Both A and B

17
New cards

If a transformer winding is completely short circuited ,several things may occur if power is applied

All of the above

18
New cards

The synchronous speed of an induction motor is found by

Multiplying the frequency by 60 and dividing the result by half the number of poles per phase

19
New cards

A series motor has a high current draw , small magnetic field and produces high torque making it ideal as a _

Starter

20
New cards

To reverse the direction of a DC motor you must reverse the direction of current in the winding of either the ____ or the ______

Arbiture, field
