Question

Which part of the motor is responsible for reversing the flow of current?

1) w
2) x
3) y
4) z

Answer 1

Brushes or a commutator in an electric motor are responsible for reversing the flow of current to maintain continuous torque and rotation direction.

Step-by-step explanation:

The part of the motor responsible for reversing the flow of current is typically known as 'brushes' or a 'commutator'. In the context of an electric motor, as the coil rotates through specific angles (specifically 0° and 180°), the current direction is reversed using these brushes or the commutator to ensure continuous rotation in the same direction. This mechanism allows the motor to convert electrical energy to mechanical energy efficiently by continuously reversing the current at these intervals to maintain the torque direction.
