In schematic diagrams, which feature represents electrical connections and components?

• A. Wires
• B. Color codes
• C. Label text
• D. Graphic symbols

Answer: (D)

Graphic symbols are what schematics use to show both what a component is and how it connects within the circuit. Each standardized symbol represents a specific component (like a resistor, capacitor, diode, or switch) and is placed at the points where it connects to wiring. The wires themselves show the paths between symbols, but they aren’t the components they connect. Color codes help identify wire function or grouping, not the actual components, and label text gives names or values rather than depicting the component shapes. So, the feature that conveys both the identity of components and their electrical connections is the graphic symbols.
