If the speed of rotation of the armature of a generator is increased, how would it effect (i) The maximum emf produced (ii) The frequency of the emf?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Maximum emf and frequency both increases
- Maximum EMF increases because the rate of change of magnetic flux increases with speed.
- Frequency increases because the number of cycles per second increases as the armature speed increases.
