🔍 Key Concepts

• AC alternator basics – what determines the frequency (Hz) of the AC produced • Relationship between rotor speed (rpm) and electrical frequency (Hz) in an alternator • Which factors affect voltage (amplitude) versus which affect frequency of the output

💭 Think About

• Which part of an alternator’s output (frequency vs voltage) is changed when you speed up or slow down the rotating magnetic field? • Do more turns of wire or stronger magnets change how many cycles per second occur, or mainly how large the voltage is in each cycle? • Is the output voltage a cause of the frequency, or is it another independent characteristic of the alternator’s output?

✅ Before You Answer

• Identify which option is directly tied to cycles per second (Hz), not to voltage level. • Separate choices that mainly affect amplitude (voltage) from the one that affects how often the waveform repeats. • Confirm that frequency is set by mechanical speed and number of poles, and decide which option actually reflects that idea.
