The only difference between the construction of DC generator and AC generator is that
Correct answer: C. commutator
- A. carbon brushes
- B. coil
- C. commutator
- D. magnetic field
Explanation
The primary difference between the construction of a DC generator (Direct Current) and an AC generator (Alternating Current) lies in the presence of a commutator. - In a DC generator, a commutator is used to convert the alternating current generated in the coil into direct current. The commutator ensures that the current flows in one direction in the external circuit- In an AC generator, there is no commutator. The generated current is alternating by nature, and it is not converted to direct current. The output of an AC generator is in the form of alternating current.

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.
