One can increase the performance.of a transformer by:
Correct answer: D. All of these
- A. Using primary and secondary wires of less resistance
- B. Making the sheets of transformer core fully insulated
- C. Using methods to increase the flux coupling between the coils
- D. All of these
Explanation
In order to improve the efficiency, to minimize all the power losses: Core should be assembled from the laminated sheets of a material whose hysteresis loop area is very small. The insulation between lamination sheets should be perfect so as to stop the flow of eddy currents. The resistance of primary and secondary coils should be kept to minimum. As power transfer from primary to secondary takes place through flux linkages, so the primary and secondary coils should be wound in such a way that flux coupling between them is maximum.

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.
