In a step-up transformer, _.
Correct answer: D. Vs>Vp
- A. Vs/Vp =1
- B. Vs<Vp
- C. Vs=Vp
- D. Vs>Vp
Explanation
Correct Option: DThis option is correct because in the step up transformers the number of the voltage in the secondary coil is greater than primary coil. As turns in the secondary coil are greater than the primary coil. Due to this Vs>Vp

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.
