🔍 Key Concepts

• How an AC generator (alternator) controls its output voltage during normal operation • The role of the field (rotating magnetic field) versus the mechanical drive speed • What can realistically be changed while the generator is running under load

💭 Think About

• Which of these options can be adjusted quickly and smoothly in real time without rewiring or stopping the machine? • In actual shipboard alternators, what do engineers typically adjust: the mechanical speed, the magnetic field strength, or something in the load? • Which choice directly affects the generated EMF (voltage) according to basic generator theory (E ∝ Φ × N × f)?

✅ Before You Answer

• Eliminate any option that would require physical modification of the windings while operating • Consider that generator speed is usually tied to fixed engine RPM needed to maintain system frequency (50/60 Hz) • Remember that power factor is mostly a characteristic of the load, not the standard control used to set generator terminal voltage
