PartC

In an AC generator, slip rings are used to:

• Provide a continuous electrical connection to the rotating coil

• Convert AC to DC

• Control the generator's speed

• Measure the generator's voltage output

The ___________ principle states that a changing magnetic field induces an electromotive force (EMF) in a conductor.

• Kirchhoff’s

• Faraday's

• Current

• Magnetic

Slip rings are conductive rings that are connected to the ___________ component of the AC generator.

• Stationary

• Rotating

• Supply

• Magnetic field

The rotating component in an AC generator that is connected to the slip rings is called:

• Rotor

• Stator

• Commutator

• Armature

The primary purpose of slip rings in an AC generator is to

• Enable the transfer of electrical energy from the rotating coil to an external circuit (without damaging the wires)

• Ensure that the generated AC voltage remains constant

• Prevent the generator from overheating

• Control the frequency of the generated AC voltage

In a DC generator, the commutator is used to:

• Change the direction of the generated DC current

• Measure the generator's voltage output

• Convert DC to AC

• Control the generator's speed

The commutator is a device that consists of a set of ___________

• Coil

• Segments

• Wood

• none of the choices

The rotating component in a DC generator that is connected to the commutator is called:

• Armature

• Magnet

• Stator

• Slip ring

The purpose of the commutator in a DC generator is to:

• Convert the alternating current (AC) produced by the generator into direct current (DC)

• Ensure that the generated DC voltage remains constant

• Prevent the generator from overheating

• Allow the generator to produce alternating current (AC)

The function of the commutator is to reverse the direction of the ___________ in the generator's armature coil.

• Current

• Voltage

• Resistance

• Power
