What do schematic diagrams use symbols to show?

• Layout of electrical systems

• Layout of mechanical systems

• Layout of both electrical and mechanical systems

• Layout of plumbing systems

How do block diagrams plan circuit functions?

• Using boxes with headings like input, process, and output

• Using triangles with categories like input, process, and output

• Using arrows with descriptions like start, process, and end

Why are schematic diagrams not drawn to scale?

• To save space on the diagram

• To make the diagram easier to understand

• To avoid looking jumbled or overly complex
