Step down transformer has _ turns in secondary coil:
Correct answer: B. Less
- A. More
- B. Less
- C. Equal
- D. Zero
Explanation
In a step-down transformer, the number of turns in the secondary coil is less than the number of turns in the primary coil. This configuration is designed to decrease the input voltage to a lower output voltage.According to the transformer equation:Vp/Vs = Np/NsSince the step-down transformer is designed to decrease the voltage, the secondary voltage Vs is less than the primary voltage Vp. Therefore, to maintain the equation, the number of turns in the secondary coil (Ns) must be less than the number of turns in 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.
