Wires that are connected to each other and are indicated by a dark circle in diagrams are called?

• A. Common wires
• B. Linked wires
• C. Connected wires
• D. Joined wires

Answer: (D)

The main idea is how circuit diagrams show wires that actually connect at a point. A dark circle marks a junction where multiple conductors come together and are electrically joined. That’s why the wires at that dot are described as joined wires—their ends are connected at that node. The other terms aren’t standard for this symbol, and “connected wires” is too generic. Also note: if lines cross without a dot, they aren’t connected.
