The function of a main transformer is to convert:
Correct answer: B. one alternating voltage to another alternating voltage of different magnitude.
- A. one direct voltage to another direct voltage of different magnitude.
- B. one alternating voltage to another alternating voltage of different magnitude.
- C. a high value alternating voltage to low value direct voltage.
- D. A high value alternating current to low value direct voltage
Explanation
A transformer converts a high voltage low current alternating current to a low voltage high current one and vice versa. Therefore the answer will be B.

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.
