Which diagram type uses actual pictures of components instead of conventional electrical symbols?

• A. Wiring diagram
• B. Installation drawing
• C. Pictorial diagram
• D. Exploded view of drawings

Answer: (C)

Pictorial diagrams use actual pictures of components instead of conventional electrical symbols. This helps technicians identify parts quickly by how they look and see how they fit together in real space. Wiring diagrams rely on symbols to represent electrical circuits, installation drawings show placement and routing without real part images, and exploded views illustrate assembly relationships with parts separated. So the diagram type that uses real images of components is the pictorial diagram.
