which of the following remains constant in a transformer?
Correct answer: D. Frequency
- A. Current
- B. Power
- C. Potential
- D. Frequency
Explanation
From relation current and voltage changes. Only for ideal transformer power remain same otherwise power also changes (decreases due to energy losses ). But the frequency in the transformer does not change.

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.
