Harmonics in transformer result in
Correct answer: D. All of the above
- A. Increases core loss
- B. Increases I2R loss
- C. Interference with communication circuits
- D. All of the above
Explanation
All of the above effects result from the presence of harmonics in transformers. Harmonics cause distortion in the magnetic flux, leading to increased core losses due to heightened hysteresis and eddy currents. Additionally, distorted current waveforms increase I2R losses in the windings. Furthermore, harmonics can introduce electromagnetic interference (EMI), disrupting communication circuits. Therefore, the correct answer is All of the above. Each individual effect contributes to the overall impact of harmonics in transformers, making option D the most comprehensive choice.

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.
