Questions and Answers 100% Pass
A so-called three-phase bridge rectifier has a minimum of ______ to rectify the AC
output of the stator windings to DC output from the rectifier. - ✔✔6 diodes (3 positive
and 3 negative)
As the rotor rotates, each time the magnetic field changes from north to south and south
to north, the polarity of each phase winding reverses and, as a result, the current
changes direction. - ✔✔True
A ripple that is inconsistent across each winding indicates that the stator windings and
diodes are each creating current flow and voltage consistently. - ✔✔False
The ______________ allow current to flow one way in the rectifier assembly. - ✔✔diodes
The voltage regulator s job is to control the output of the alternator so that the system
voltage is maintained within specified limits. - ✔✔True
In the delta method, the windings are connected in the shape of a square. - ✔✔False

, In a Wye type stator, each winding is always part of a complete circuit, and when
current is flowing, it is always flowing through two series windings at the same time. -
✔✔True
The alternator consists of a stationary winding assembly called the stator, a rotating
electromagnet called the rotor with a slip ring, a brush assembly, a rectifier assembly,
__________, and a cooling fan and drive pulley. - ✔✔Two end frames
The rotor is an electromagnet that rotates freely in the alternator. - ✔✔True
The stationary winding assembly in an alternator is called the: - ✔✔stator
The main purpose of the slip rings and brushes is to: - ✔✔making an electrical
connection with the rotor winding.
Alternators operate at _____wattage output at ____ rpm. - ✔✔Greater; lower
The key difference between an alternator and a DC generator is which component
rotates or moves to generate electricity. - ✔✔True
In the rotor, the magnetic field is created by the alternator, which rotates within the
stationary stator windings to generate electricity there. - ✔✔False
In addition to recharging the battery the alternator is required to: - ✔✔supply current to
the electrical circuits.
