Which one of the following is not present in A.C generator?
Correct answer: D. commutator
- A. Armature
- B. magnet
- C. slip rings
- D. commutator
Explanation
D is the correct answer. A.C. generators do not have a commutator. A commutator is a component found in DC generators, which is responsible for converting the alternating current induced in the armature windings into direct 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.
