Question

Statement I: For continuous rotation of the coil in the same direction, the current in the coil must be reversed.

Statement II: In electric motors, the direction of current is reversed using split rings.

• A. Only statement I is correct.
• B. Only statement I is correct.
• C. Both the statements are correct.
• D. Both the statements are incorrect.

Answer 1

The correct option is C Both the statements are correct.

Split ring is used for reversing the direction of current in the coil. For the continuous rotation of the coil in the same direction, the current in the coil must be reversed. Therefore, after every half rotation of the coil the direction of the couple rotating the coil remains the same and the coil continues its rotation in the same direction.
