Which item is used to show how connections are made between electronic components?

• A. Amplifier
• B. Amperes
• C. Ohms
• D. Circuit diagrams

Answer: (D)

Circuit diagrams show how connections are made between electronic components. They use standardized symbols for components and lines for wires, so you can trace exactly which parts connect and how current would flow through the circuit. This makes it possible to design, assemble, and troubleshoot electronics accurately. The other items aren’t diagrams: an amplifier is a device that boosts signals, amperes are a unit of current, and ohms are a unit of resistance. They describe aspects of circuits, but don’t illustrate the wiring and connections.
