🔍 Key Concepts

• Sound-powered telephone circuits on ships often separate how you call (ring) from how you talk. • A common circuit means all stations share the same pair of talking wires; a selective circuit means a station or number must be chosen to complete that part of the circuit. • In the illustration, each station has a selector switch with numbers and a separate set of connections for the handset/talking circuit.

💭 Think About

• Look at the bundle of lines running straight across between all stations versus the lines that go through the selector dial: which set appears to be shared by every station without needing a selection? • When a station is set to ring another numbered station (e.g., "Rings on #4"), which part of the diagram actually changes path when you move the selector: the ringing wires or the talking wires? • After the call is set up and answered, does the diagram suggest that everyone could listen in on the conversation, or only the two selected stations? What does that imply about whether the talking path is common or selective?

✅ Before You Answer

• Identify which conductors are continuous across all four stations; that part of the system is operating as the common circuit. • Trace the path from the ringer/induction coil through the numbered selector switch; the circuit that depends on the selector position is the selective one. • Before choosing an option, be sure you can state in your own words: "In this diagram, the _______ circuit is common, and the _______ circuit is selective, because of how the wiring and selector switch are arranged."
