If 1 transformer has 500 turns on the primary coil and 250 turns on the secondary coil, then
Correct answer: A. Output voltage is half of input voltage
- A. Output voltage is half of input voltage
- B. Output and input voltages are equal
- C. Output voltage is double the input voltage
- D. Output voltage is zero
Explanation
Using formula; Np/Ns = Vp/ Vs 500/250 = Vp/Vs 2 = Vp/Vs So Vp = 2Vs or Vs = Vp/2 Hence, secondary voltage or output voltage is half of input or primary voltage. So, option A is correct.

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.
