DC generators are used solely for mechanical power.

A DC generator only produces AC electricity.

No, a DC generator cannot produce electricity.

Yes, a DC generator can produce electricity.

Brushes help in increasing the motor's speed.

Brushes are used to cool the motor components.

Brushes are responsible for the motor's structural support.

Brushes in a DC motor provide electrical contact to the rotating commutator, allowing current to flow and enabling motor operation.
