Which statement describes a schematic diagram?

• A. A Map of an Electronic Circuit Using Symbols to Represent Electrical Components Along the Pathway
• B. Shows Major Configuration of a System and Its Inner Connections
• C. A Step-By-Step Maintenance Procedure
• D. A Floor Plan of a Building’s Electrical System

Answer: (A)

A schematic diagram represents circuits using symbols to show how components connect and how signals flow, focusing on the logical relationships rather than physical layout. The statement describing a map of an electronic circuit using symbols to represent electrical components along the pathway captures exactly that idea, since it emphasizes standard symbols and the connections between parts. The other descriptions point to different kinds of diagrams: showing a system’s major configuration and inner connections can be a more general system or block diagram; a step-by-step maintenance procedure is about instruction sequences; and a floor plan depicts physical layout rather than the symbolic connections of a circuit.
