Question 1 of 27070

An AC generator produces 60 Hz at 1800 RPM. If the generator speed is increased to 1830 RPM, what will happen to the frequency in Hz?

🔍 Key Concepts

• Direct relationship between speed and frequency in an AC generator • Proportional change: small change in RPM → proportional change in Hz • How to compare percent change in RPM to percent change in frequency

💭 Think About

• If 1800 RPM gives 60 Hz, what is the ratio of Hz per RPM? Use that to estimate the new frequency at 1830 RPM. • Is the speed change large or small? Based on that, should the frequency change be by 1 Hz, 3 Hz, or something smaller? • Think about whether frequency can stay exactly the same if the mechanical speed has clearly changed.

✅ Before You Answer

• Calculate the percentage change in RPM from 1800 to 1830 and apply the same percentage to 60 Hz. • Check whether the resulting frequency is closer to 60 or 61 Hz, then see which answer choice best matches. • Verify that frequency is directly proportional to RPM for a given number of poles in the generator (no change in poles here).
