Write short note on DC Generator. |

Answer» The output produced here is unidirectional. The slip rings are replaced with split rings to achieve this. To get a direct current (DC) generator a split-ring type commutator must be used. In this arrangement, one brush is at all times in contact with the arm moving up in the field while the other is in contact with the arm moving down. Thus a unidirectional current is produced in such a generator. The output produced here is unidirectional. The slip rings are replaced with split rings to achieve this.
