In step up transformer when the alternating voltage increases then the alternatingcurrent

Correct answer: B. Will decrease.

  • A. Will increase.
  • B. Will decrease.
  • C. Will not change
  • D. None of the above

Explanation

In a step-up transformer, the secondary voltage V2 is greater than the primary voltage V1. Since the product of voltage and current is constant, an increase in voltage V2 results in a decrease in current I2 in the secondary coil. The formula is given by:I1V1=I2V2

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.
