An AC generator converts:
Correct answer: B. Mechanical energy to electrical energy
- A. Mechanical energy to heat energy
- B. Mechanical energy to electrical energy
- C. Electrical energy to mechanical energy
- D. Heat energy to electrical energy
Explanation
A generator can convert mechanical/kinetic energy to electrical energy. It can produce either AC or DC current. An AC generator creates an alternating current that periodically reverses direction. But in a DC generator, a direct current flows in one direction.

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.
