In a step-up transformer, the number of turns in _
Correct answer: B. primary are more
- A. primary are less
- B. primary are more
- C. primary and secondary are equal
- D. primary are infinite
Explanation
In a step-up transformer, the primary coil has fewer turns than the secondary coil. The transformation ratio (turns ratio) of a transformer is defined as the ratio of the number of turns in the secondary coil Ns to the number of turns in the primary coil Np. For a step-up transformer, this ratio is greater than 1, indicating that the secondary has more turns than the primary.

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.
