Which diagram shows all circuit components and how they are connected?

• A. Electric circuit
• B. Circuit diagram
• C. Magnetism
• D. Ohm

Answer: (B)

Understanding how components connect in a circuit is shown most clearly by a circuit diagram. This diagram uses standard symbols for elements like resistors, batteries, and switches, with lines representing the wires and their connections. It focuses on the topology—the way components are linked—so you can see which parts are in series or parallel and how current would flow, without worrying about the physical layout. An electric circuit refers to the actual built hardware, magnetism is the study of magnetic fields, and Ohm is a unit (or a person) not a diagram. So the diagram that shows all components and exactly how they’re connected is the circuit diagram.
