In principle, the transformer consists of two coils of copper, electrically insulated from each other, wound on the same?
Correct answer: A. Iron core
- A. Iron core
- B. Copper core
- C. Gold core
- D. Steel core
Explanation
The correct statement is A. Iron core. In principle, transformers consist of two coils of copper wire wound on the same iron core. The iron core enhances the magnetic coupling between the coils, allowing for efficient energy transfer in the transformer.

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.
