What is a drawing that shows electrical connections and components of a circuit arrangement?

• A. Wiring diagram
• B. Schematic diagram
• C. Block diagram
• D. Pictorial diagram

Answer: (B)

A schematic diagram uses standardized electrical symbols and lines to show how components connect and interact in a circuit. It focuses on the function and signal paths rather than how things physically appear or are laid out, which makes it ideal for understanding how current flows and how the circuit operates. The other diagram types serve different purposes: wiring diagrams map the actual wires, routes, connectors, and harnesses; block diagrams show broad functional blocks and their relationships; and pictorial diagrams depict components in a realistic view for identification. Therefore, the drawing that shows electrical connections and components of a circuit arrangement is a schematic diagram.
