What is the frequency of the AC power generated in the United States and Canada?

The frequency of the alternating current (AC) power generated in the United States and Canada is 60 Hz. This means that the current alternates 60 times per second. The choice of 60 Hz is primarily historical, as it was adopted for electric power systems in the early days of electrical engineering and has been standardized across much of North America since then.

This frequency is significant because it impacts the design and functioning of electrical appliances and systems, ensuring compatibility and efficiency across different devices and the power grid. Using 60 Hz allows for optimal performance of electric motors and other devices designed for this frequency, contributing to the overall reliability and efficiency of the electrical infrastructure in these regions.

In contrast, other frequencies mentioned in the options are less common in North America. For example, 50 Hz is typically used in many parts of Europe and Asia, while 100 Hz and 30 Hz are not standard frequencies for commercial power systems.
