A generator manufacturing company accidentally made an AC generator instead of a DC generator. To fix this error,

  1. the magnetic field needs to be made stronger
  2. the slip rings should be replaced with split rings ✓
  3. the number of turns of the armature coil needs to be decreased
  4. the split rings should be replaced with slip rings
Explanation

Slip rings give an alternating current in the outside circuit. Split rings (a commutator) reverse the connection every half turn, so the current flows one way only.

To turn the AC generator into a DC generator, the slip rings should be replaced with split rings.
