Question

Why slip rings in an alternator are necessary?

• A. They permit the stator to rotate
• B. They provide a high resistance connection to the stator windings
• C. They prevent a delta from forming.
• D. They permit current to flow through a rotating component called the rotor

Hint:

Slip rings help in maintaining the efficiency of the alternator by ensuring uninterrupted current flow as the rotor moves, which is crucial for the alternator's functionality in generating power.

Answer 1

The Correct Option is D

Slip rings in an alternator are essential for allowing electrical current to be transferred from the rotor, which rotates, to the electrical system without twisting the wires. They act as electrical contacts and maintain continuity as the rotor spins.
