[amp_mcq option1=”armature” option2=”brush” option3=”commutator” option4=”loop E. None of the above” correct=”option1″]
The correct answer is: A. armature.
The armature is the rotating part of an electric motor that converts electrical energy into mechanical energy. It is made up of a coil of wire that is wrapped around a metal core. When an electric current is passed through the coil, it creates a magnetic field. This magnetic field interacts with the magnetic field of the stator, which is the stationary part of the motor, and causes the armature to rotate.
The other options are incorrect because:
- B. Brushes are used to conduct electricity to the armature.
- C. The commutator is a device that reverses the current in the armature coil as it rotates.
- D. A loop is a simple shape that is used to represent a coil of wire.
- E. None of the above is the correct answer.
