🔍 Key Concepts

• Generator voltage control and what actually changes when you adjust it • Difference between prime mover speed control (governor) and voltage control • Role of field excitation in producing generator output voltage

💭 Think About

• Ask yourself: Does voltage get controlled by changing mechanical speed, electrical load, or something inside the generator’s magnetic field? • Which device is normally responsible for keeping frequency constant, and which device keeps voltage constant? • When the ship’s electrical load changes, what must be adjusted so that the generator’s terminal voltage stays steady?

✅ Before You Answer

• Identify which choice deals with mechanical speed control (governor action) versus electrical excitation • Eliminate any option that confuses protective devices (like overvoltage relays) with control devices (like regulators) • Focus on the option that directly affects the generator’s magnetic field strength to hold voltage constant under varying load
