What is the typical frequency of residential AC power in North America?

The typical frequency of residential AC power in North America is indeed 60 Hertz. This frequency has become the standard for electrical systems in North American homes and businesses, allowing for efficient operation of most household appliances and tools.

The choice of 60 Hertz was established during the early development of electrical systems and has remained consistent due to the compatibility of equipment designed for this frequency. It allows transformers, motors, and other electrical devices to operate efficiently without losing performance.

In contrast, other frequencies such as 50 Hertz, common in many parts of the world such as Europe and Asia, reflect different historical developments in electrical systems. Frequencies like 30 Hertz and 100 Hertz are not standard for residential power and are not typically used in general infrastructure. Therefore, 60 Hertz is recognized as the correct answer due to its prevalence and historical significance in North American electrical systems.
