🔍 Key Concepts

• How sound-powered telephones are designed to work during a total power failure • Whether the circuit depends on the ship's electrical distribution system or is independent of it • The basic idea of converting mechanical energy (sound/vibration) into electrical signals

💭 Think About

• If the ship lost all electrical power, which of these options would still allow the sound-powered phones to work? • Which choice describes a system that is built into the phone handset itself, rather than supplied from elsewhere on the ship? • Think about what part of the system is actually moving or vibrating when a person speaks into the handset.

✅ Before You Answer

• Confirm whether sound-powered circuits must operate during a blackout for damage control and emergency communications • Check which options (A, B, C) rely on the ship’s installed electrical power versus something generated locally • Ask yourself: does the system name 'sound-powered' give a clue about which energy source is being used?
