🔍 Key Concepts

• AC generator (alternator) basics – what parts actually create the voltage output • Difference between prime mover speed (frequency control) and field excitation (voltage control) • What determines frequency (hertz) vs what determines voltage (volts) in an alternator

💭 Think About

• Ask yourself: Which part of the generator’s operation mainly affects the output frequency rather than the voltage level? • Which adjustment directly changes the strength of the magnetic field linking the stator windings? • Do load changes or number of poles normally get changed while the machine is in service to regulate output voltage?

✅ Before You Answer

• Identify which choice is associated with magnetic field strength in the rotor (excitation) • Separate in your mind: speed → frequency, magnetic field strength → voltage • Confirm that number of poles is a fixed design feature, not something routinely varied during normal operation
