Transformation ratio of transformer is given by:
Correct answer: A. Vs/Vp
- A. Vs/Vp
- B. IpIs
- C. NsNp
- D. All of these
Explanation
The transformation ratio is defined as the ratio of output voltage to the input voltage of the transformer. Vs is output voltage (secondary) and Vp is the input voltage (primary voltage).

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.
