The part of an electric motor that reverses the direction of flow of current in it is?
ABrush
BSplit ring
CSoft iron core
DCoil
Answer:
B. Split ring
Read Explanation:
In an electric motor, the split ring commutator reverses the direction of current, allowing for continuous rotation of the motor in one direction
A split-ring commutator is essential in a d.c. motor because it reverses the direction of current in the coil every half turn.
This ensures that the torque acting on the coil is always in the same direction, allowing continuous rotation.
