The out put of a dynamo using a split ring commutator is
The out put of a dynamo using a split ring commutator is
- A. dc
- B. ac
- C. fluctuating dc
- D. half wave rectified da
Step-by-step solution
A dynamo with a split ring commutator converts the alternating current generated in the armature into direct current. However, the output voltage is not constant; it varies as the coil rotates, resulting in a pulsating or fluctuating DC waveform. Therefore, the output is fluctuating DC, not pure DC or AC.
