What is the name of an electrical wiring diagram that uses standard component symbols?

The correct answer is a schematic. A schematic diagram provides a visual representation of an electrical circuit using standard symbols to denote different components, such as resistors, capacitors, and power sources. These symbols are universally recognized within the field of electronics, allowing technicians and engineers to understand circuit behavior and design without ambiguity.

In contrast, a bill of materials lists components and parts needed for a project, but does not provide visual representation or wiring connections. A connector pinout illustrates the specific connections and functionality of individual pins in a connector but does not depict the overall circuit and its layout. A flow chart is used for depicting processes or algorithms, not electrical circuits, and thus does not use component symbols at all.
