What eliminates any possible sparking to the brush guides caused by the movement of the brushes within the holder in a generator?

  1. The commutator

  2. The slip ring

  3. The brush pigtail

  4. 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.
