I think the correct answer from the choices listed above is the third option. The function of the slip rings in an electric generator would be producing a path for current to flow. Hope this answers the question. Have a nice day. Feel free to ask more questions.
An AC generator is a device that converts mechanical energy into electrical energy using the principle of electromagnetic induction.
<em><u>Slip rings are two hollow rings to which two ends of the armature coil are connected. These rings rotate with the rotation of the coil. They function to to allow for electrical contact with the brushes.</u></em>
Slip rings therefore, provide a means for connecting the rotating armature to an external circuit.
