🔍 Key Concepts

• Role of a small DC machine in supplying field current to a larger AC generator • Difference between stationary and rotating parts of a generator (stator vs rotor) • Function of an armature compared to a device that only supplies field current

💭 Think About

• Which component’s main job is to supply DC current to the field windings of an AC generator, rather than generate the main AC output? • Among the options, which terms name physical parts of a generator, and which term names a separate device associated with the generator? • Think about what you would call a small DC generator mounted on or near a larger AC generator to provide its magnetizing current.

✅ Before You Answer

• Identify which option is specifically a separate DC device that feeds current to the field of the main generator. • Confirm that stator and rotor refer to stationary and rotating parts of a machine, not a separate supply machine. • Verify that an armature is typically the power-producing winding, not the auxiliary DC supply to the main generator.
