🔍 Key Concepts

• Role of brushes in DC machines (motors and generators) • Difference between current collection and magnetic effects like armature reaction • What component normally provides excitation/field current in a DC generator

💭 Think About

• Think about where the current is produced in a DC generator and how it gets out to the external circuit. • Which part of the machine actually touches the rotating commutator and stationary external wiring? • Ask yourself: do brushes mainly deal with magnetism, conversion of current type, or with making an electrical connection?

✅ Before You Answer

• Identify which component (brushes, commutator, field windings) is responsible for mechanical-to-electrical connection. • Distinguish between what controls the magnetic field (excitation) versus what carries the load current. • Eliminate any choice that describes a function usually done by the field windings or by the commutator, not by the brushes themselves.
