Question

In which device does the split ring act as a commutator?

• A. Electric motor
• B. Galvanometer
• C. Voltmeter
• D. Electric generator

Hint:

A split ring commutator in an electric motor reverses current direction to maintain continuous rotation.

Answer 1

The Correct Option is A

Step 1: Understanding the function of a commutator. A split ring commutator is used in electric motors to reverse the direction of current, ensuring continuous rotation in one direction.
Step 2: Explanation of incorrect options.
- Galvanometer, Voltmeter, and Electric generator do not use a split ring commutator for rotation control.
