🔍 Key Concepts

• Older gyro compass power supplies and how they obtain a stable DC voltage from the ship's AC power • What a carbon pile regulator does in electrical systems (general electrical engineering concept) • Why stable voltage/current is important for sensitive instruments like a gyro compass

💭 Think About

• Ask yourself: which of these answer choices describes an electrical function rather than a mechanical or dynamic one? • Think about which components in a gyro compass system would deal with electrical input quality versus those that control the gyro's physical motion (precession, pendulum effect, etc.). • Consider where a carbon pile would be located: in the compass mechanism itself, or in the power/control circuitry feeding the gyro motor and control coils?

✅ Before You Answer

• Identify which choices deal with electrical regulation versus mechanical/gyrodynamic behavior. • Recall or look up what a carbon pile regulator is used for in classic shipboard DC systems. • Verify which part of the gyro compass system would need a device made of stacked carbon discs that change resistance under pressure.
