Q

What will be the frequency of a three-phase, 16 pole, AC generator operating at 3000 revolutions per minute?

🔍 Key Concepts

• Relationship between speed (RPM), number of poles, and frequency for synchronous AC generators • How many pole pairs a 16‑pole machine has • Unit consistency when using formulas (RPM vs. Hz)

💭 Think About

• Recall or look up the standard formula that links synchronous speed, number of poles, and frequency in an AC generator, then solve for frequency when speed and poles are known. • First, convert the generator speed into a form that works neatly in the formula (or use the constant that handles RPM directly). • Think about how more poles affect the frequency at a fixed speed: does adding poles increase or decrease the frequency?

✅ Before You Answer

• Be sure you are using poles, not pole pairs, correctly in the formula. • Check that your units are consistent: revolutions per minute (RPM) versus cycles per second (Hz). • After calculating, compare your numerical result with the answer choices and see which is closest to your computed frequency.
