In an A.C. generator, the presence of slip rings is essential for the collection of the generated alternating current. Unlike a direct current generator, which uses a commutator ring to convert the generated alternating current into direct current, an A.C. generator continuously produces alternating current as the rotor spins. The slip rings allow the current to flow out of the generator without being rectified, maintaining the alternating nature of the current.

The slip rings provide a continuous electrical connection with the external circuit, enabling the alternating current to pass through without interruption, which is critical for the operation of A.C. generators. This design is fundamental to the efficiency and functionality of A.C. generators, allowing them to deliver the power needed for various applications. The other options, such as transformers, induction coils, and rectifiers, are not components of A.C. generators but rather serve different purposes in electrical engineering and power distribution.
