Question

The number of slip rings in a simple AC generator is \dots

• A. two
• B. one
• C. three
• D. zero

Hint:

Remember:
• AC Generator $\rightarrow$ Two Slip Rings
• DC Generator $\rightarrow$ One Split Ring Commutator

Answer 1

The Correct Option is A

Concept: An AC generator converts mechanical energy into electrical energy in the form of alternating current using electromagnetic induction.

Step 1: Recall the main parts of an AC generator. A simple AC generator contains:
• Armature coil
• Magnetic field
• Two slip rings
• Two carbon brushes

Step 2: Understand the role of slip rings. The ends of the rotating coil are connected to circular metallic rings called slip rings. These rings rotate with the coil and maintain continuous electrical contact with the external circuit through carbon brushes.

Step 3: Determine the number of slip rings. Since both ends of the coil must remain connected during rotation, a simple AC generator uses: \[ \boxed{2 \text{ slip rings}} \] Hence, the correct answer is option (1).
