When interpreting an electrical wiring diagram, what does a solid line typically indicate?

• A. A ground reference path.
• B. A power supply line.
• C. A conductor path or wire connection between components.
• D. A shielded cable.

Answer: (C)

Solid lines in electrical wiring diagrams represent a conductor path or wire connection between components. This shows there is a direct electrical link through which current can flow from one point to another. Ground paths are indicated by lines terminating at a ground symbol, not just by being solid lines. Shielded cables are shown with shielding symbols or a separate notation around the conductor, not by a plain solid line alone. A power supply line would be depicted by a connection to a voltage source symbol, rather than inferred from the line itself.
