The grounded secondary conductor is correctly identified as the neutral.

• A. Grounded secondary conductor
• B. Un-Grounded conductor
• C. Shield conductor
• D. Grounding electrode conductor

Answer: (A)

In electrical systems, the neutral is the grounded conductor—it's the conductor that is intentionally bonded to earth to establish a reference point and provide a return path for current. On a transformer, the secondary often has two ungrounded conductors (hots) plus one conductor that is tied to earth at the service equipment. That grounded secondary conductor is what we call the neutral. Why this is the best answer: the neutral is defined as the grounded conductor, meaning it is connected to earth, unlike the ungrounded conductors (hots) that carry current without a direct earth bond. The shield conductor is used for shielding in some cables and is not the neutral, and the grounding electrode conductor is the wire that connects the system to the earth for safety grounding—its role is not to serve as the normal current-return path.
