What eliminates any possible sparking to the brush guides caused by the movement of the brushes within the holder in a generator?
The commutator
The slip ring
The brush pigtail
A dampening fluid
The correct answer is: The brush pigtail
In a generator, the brush pigtail eliminates any possible sparking to the brush guides caused by the movement of the brushes within the holder. The brush pigtail serves as a flexible connection that allows the brushes to move with minimal friction and sparking. The commutator and slip rings play roles in the electrical connection and transfer of current, while a dampening fluid is not typically used in this context.
