cmf generated by A.C dynamo depends upon_____________?
Correct answer: D. all of above
- A. number of turns in the coil
- B. magnetic field strength
- C. frequency of rotation
- D. all of above
Explanation
For an AC dynamo, generated emf is proportional to the number of turns, magnetic flux or field strength, and rotational speed or frequency. Therefore, all three listed factors affect the emf.
