Part of a DC generator that transmits the current to its external circuit is referred to as?

• A. Brushes
• B. Commutator
• C. Armature
• D. Slip rings

Answer: (A)

The part of a DC generator that transmits the current to its external circuit is known as brushes. Brushes are conductive elements that maintain contact with the rotating commutator, allowing the electric current to flow from the armature windings to an external circuit. In a DC generator, as the armature spins, the brushes slide across the commutator segments. This interaction ensures that the current direction is rectified, meaning it converts the alternating current generated in the armature into a direct current output suitable for external use. Brushes are typically made from materials like carbon and are critical for efficient electrical contact and current transmission. While the commutator also plays a critical role by serving as the interface between the armature and the external circuit, it does not directly carry the current to the external load. Instead, it works in conjunction with the brushes. The armature refers to the rotating part of the generator, which generates the electrical power, but it is the brushes that facilitate the actual transmission of that power. Slip rings, on the other hand, are used in alternating current (AC) systems to maintain electrical connections with rotating components, which distinguishes them from the specific function of brushes in a DC generator.
