To improve efficiency of transformer the flux coupling b/w primary & secondary coil should be

Correct answer: B. Maximum

  • A. Small
  • B. Maximum
  • C. May be small or may be maximum
  • D. Zero

Explanation

This option states that the flux coupling between the primary and secondary coil should be at its maximum to improve efficiency. This is correct because a higher degree of flux coupling ensures better energy transfer between the coils.

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.
