In a step-up transformer, _ is increased in the secondary coils.

Correct answer: C. Number of turns

  • A. Electric field
  • B. Magnetic field
  • C. Number of turns
  • D. None of these options is correct

Explanation

A transformer that increases the voltage from primary to secondary (more secondary winding turns than primary winding turns) is called a step-up 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.
