🔍 Key Concepts

• Difference between slip rings and commutators in rotating electrical machines • How DC excitation is supplied to the rotating field of an AC generator (alternator) • Roles of brushes, rotor field windings, and exciter output

💭 Think About

• Ask yourself: In an AC generator, which component allows a continuous DC current to be fed into a rotating field winding without reversing its direction? • Think about which device (slip rings or commutator) is normally associated with AC generators versus DC generators. • Consider whether a rotating bar magnet or arc-over protection can actually conduct and maintain DC current into a rotating field winding.

✅ Before You Answer

• Verify which device is used in AC alternators to connect stationary brushes to a rotating field winding. • Confirm which device (slip ring vs commutator) is specifically used to reverse current direction each half turn, and whether that is desired here. • Make sure the option you pick is a physical means of transferring current into the rotor, not a purpose (like reducing arcing) or an unrelated component.
