If the supply frequency of a transformer increases, the secondary output voltage of the transformer:
Correct answer: A. Increases
- A. Increases
- B. Decreases
- C. Remains unchanged
- D. All of the above
Explanation
If the supply frequency of a transformer increases, the secondary output voltage of the transformer increase. A transformer is designed for some constant parameters like frequency. So if the frequency increases, the secondary voltage or emf increases.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
