When a step-up transformer delivers high voltage then the current will be:
Correct answer: B. Decreased
- A. Remain same
- B. Decreased
- C. Increased
- D. Maximum
Explanation
When a step-up transformer increases the voltage, the corresponding effect on the current is inverse: the current will decrease. This relationship follows the principle of conservation of power in an ideal transformer where the product of the voltage and the current remains constant (neglecting losses). Therefore, when the voltage is increased, the current will decrease to maintain the conservation of power (P = V x I).

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.
