What is the standard frequency of AC generators in North America?

• A. 50 hertz
• B. 60 hertz
• C. 70 hertz
• D. 100 hertz

Answer: (B)

The standard frequency of AC generators in North America is 60 hertz. This frequency has been adopted for most electrical power transmission systems and is crucial for maintaining the proper operation of household appliances, industrial machinery, and the overall electrical grid. Using a consistent frequency across the power distribution system ensures compatibility and efficiency, allowing equipment designed for this frequency to operate correctly without risk of malfunction or damage. In contrast, other regions, such as Europe, typically use a frequency of 50 hertz, which illustrates the variability in standards worldwide but reinforces that North America has standardized on 60 hertz for its electrical systems. Frequencies such as 70 hertz or 100 hertz are not commonly used in general AC power distribution and would create compatibility issues with existing equipment and appliances designed for the standard frequencies.
