Which of the following losses in a transformer is zero even at full load?
Correct answer: D. Friction loss
- A. Eddy current loss
- B. Core loss
- C. Copper loss
- D. Friction loss
Explanation
Friction losses are involved with rotating parts of a machine. A transformer is a static device i.e. it does not consist of any type of moving component, due to which there is no frictional loss in the transformer irrespective of the loading condition. Hence, D is the correct option

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.
