Which term describes a diagram symbol that shows two wires are connected?

• A. Joined wires
• B. Unjoined wires
• C. Crossed wires
• D. Isolated wires

Answer: (A)

Two wires that are connected in a diagram are shown as joined at a junction, meaning they share a connection that current can use to flow from one wire to the other. That’s why the term joined wires is the best description: it communicates that the conductors are linked at that point. The other options describe wires that aren’t connected—unjoined means no connection, crossed wires may or may not be connected depending on markings (without a connection marker they aren’t), and isolated wires are not connected to anything. So “joined wires” correctly captures the idea of a diagram symbol indicating a connection.
