In a DC electric motor, a pair of split rings is used as a commutator.

• A. True
• B. False

Answer 1

The correct option is A True

True, In DC electric motor, a pair of split rings is used as a commutator.

The direction of current must be reversed every half turn; otherwise the coil comes to halt again. So, to keep torque on DC motor from reversing every time, the coil moves through the plane perpendicular to magnetic field. This achieved using a conducting ring split into two, called split ring or commutator.
