When several wires follow the same path, they may be represented as a ___________ line on a wiring diagram.

In wiring diagrams, when several wires follow the same path, this is often represented as a single thick line. This representation helps to simplify the diagram and reduce clutter, making it easier to read and understand the overall circuit design. By using a thick line, it clearly signals to the viewer that multiple conductors are being represented together, rather than showing each individual wire, which could overwhelm the diagram with too many separate lines. This method enhances clarity while still communicating the necessary information about the wiring configuration.

Other representations, like dashed or multiple thin lines, do not effectively convey the same meaning or simplicity. A dashed line generally indicates an alternate path or a wire that is not continuously connected, while multiple thin lines can suggest that individual wires are running separately rather than in a bundle. A solid line typically indicates a single wire or connection, which does not accurately reflect the presence of multiple wires in one path.
