🔍 Key Concepts

• AC frequency in an alternator (cycles per second / Hertz) • Relationship between rotor speed (RPM) and electrical frequency (Hz) • The basic formula: frequency depends on speed and number of poles, not on load or voltage regulation

💭 Think About

• When the main engine or prime mover speeds up or slows down, what happens to the frequency of the AC power on board? • Does changing resistance in a field circuit or adjusting a voltage regulator mainly affect voltage or frequency? • Which part of the alternator’s operation actually causes how many times per second the magnetic field cuts the stator windings?

✅ Before You Answer

• Identify which option is directly tied to mechanical rotational speed of the alternator shaft. • Eliminate any options that primarily control voltage output rather than frequency. • Recall that the electrical frequency (Hz) of an alternator is set by shaft speed and poles, not by load, resistance, or voltage regulator settings.
