For a step-down transformer, Ns _ Np.
Correct answer: B. Less than(<)
- A. Equal to(=)
- B. Less than(<)
- C. Greater than(>)
- D. Not equal
Explanation
A step down transformer produces a smaller output voltage than the input voltage provided to it. In order to achieve less output voltage, Vs, in the secondary coil, the number of turns on the secondary coil, Ns, should be less than the number of turns on the primary coil, Np.

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.
