What is the diagram used to show a direct connection from point A to B for conductors?

• A. Wiring diagram
• B. Schematic
• C. Single-line diagram
• D. Block diagram

Answer: (A)

Wiring diagrams show the actual physical wiring path and connections between points. They depict the real conductors, routes, terminal points, and color codes needed to link A to B, so you can install or troubleshoot the exact wiring as it exists. A schematic, by comparison, uses symbols to represent components and their functional relationships rather than how wires run in the real world. A single-line diagram abstracts multiple conductors into a single line to illustrate power distribution, not the physical routing. A block diagram focuses on high-level system functions and data or signal flows without showing wiring details. So for showing a direct physical connection between two conductors, a wiring diagram is the best choice.
