AC aircraft charge batteries using this combination.
What are transformer and rectifier?
Series motors draw the most current at this condition.
What is low RPM (startup)?
Capacitors must be this before removal.
What is discharged?
Voltage drop depends on resistance, current, and this.
What is length?
This system uses an electromagnet rotor.
What is Autosyn?
An inverter uses this to convert DC to AC.
What is an oscillator?
This motor characteristic drops as counter EMF increases.
What is current?
Grounding prevents buildup of this.
What is static charge?
Wire size is based on current capacity and this.
What is allowable voltage drop?
This system uses a permanent magnet rotor.
What is Magnesyn?
Overvoltage protection works by opening this circuit.
What is the field circuit?
Direction of rotation is reversed by changing this.
What is field or armature polarity?
This battery failure results from excessive heat and current.
What is thermal runaway?
Larger AWG numbers indicate this.
What is smaller wire?
These systems indicate position of flaps and landing gear.
What are selsyn systems?
A voltage regulator controls output by varying this resistance.
What is field circuit resistance?
This type of motor wiring connects field in parallel with armature.
What is shunt motor?
Automatic reset breakers are this in aircraft.
What is not allowed?
An 18 AWG wire example produced approximately this voltage drop.
What is 4 volts?
These systems transmit information electrically from one point to another.
What are synchro systems?
Equalizer circuits do this between generators.
What is balance load output?
These are the 4 main parts of a DC motor.
What are armature, field, brushes, end frame?
A current limiter is best used in this type of circuit.
What is heavy power circuit?
Generator ratings are expressed in this.
What is amperes at rated voltage?
Microswitches are primarily used as these.
What are limit switches?
