Question
In a DC electric generator, ________remains fixed and ______ rotates.
- Brushes, Commutator
- Magnets, Brushes
- Commutator, Magnets
- Commutator, Brushes
Hint:
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.
