The output voltage of a transformer is 3 times the input voltage, then the turns ratio will be
Correct answer: B. 3
- A. 1/3
- B. 3
- C. 1
- D. 6
Explanation
The turns ratio (\(N\)) of a transformer is the ratio of the number of turns in the secondary coil (\(N_s\)) to the number of turns in the primary coil (\(N_p\)). It is given by the equation:\[ N = \frac{V_s}{V_p} \]Given that the output voltage (\(V_s\)) is 3 times the input voltage (\(V_p\)), the turns ratio is:\[ N = \frac{3V_p}{V_p} = 3 \]Therefore, the correct option is (b) 3.

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.
