Commutator in DC generator is used to:

  1. Increase efficiency
  2. Convert AC armature current to DC
  3. Collect current
  4. Reduce losses

Correct answer: 2. Convert AC armature current to DC

Explanation: The main purpose of the commutator is to convert AC armature current to DC. In a DC generator, as the armature rotates, the alternating current induced in the armature windings needs to be converted into direct current. The commutator achieves this by providing unidirectional current flow to the external circuit.
