Question

In a DC electric generator, ________remains fixed and ______ rotates.

  1. Brushes, Commutator
  2. Magnets, Brushes
  3. Commutator, Magnets
  4. Commutator, Brushes

hintHint:

In a DC electric generator, brushes remain fixed and the commutator/split ring rotates.

The correct answer is: Brushes, Commutator


    In a DC electric generator, brushes remains fixed and the commutator rotates.
    • The brush in the AC generator creates a connection between the generator and the load and doesn't move.
    • The commutator or the split ring helps to convert the AC into pulsating DC.
    • It helps the current flow in one direction by reversing the current.
