Question
Which parts of an electric motor reverse the direction of current in the coil?
- Brushes
- Split rings
- Armature
- Magnets
Hint:
In an electric motor, a rectangular coil is suspended between the two poles of a magnetic field. The electric supply to the coil is connected with a commutator
The correct answer is: Split rings
- A commutator reverses the direction of current in the coil of a motor.
- In an electric motor, a rectangular coil is suspended between the two poles of a magnetic field. The electric supply to the coil is connected with a commutator. Commutator is a device which reverses the direction of flow of electric current through a circuit
- The split ring in the electric motor also known as a commutator reverses the direction of current flowing through the coil after every half rotation of the coil. Due to this the coil continues to rotate in the same direction.
- so split rings is answer.
