Why is 60Hz AC used in America? What are the advantages and disadvantages of using 60Hz?
What is the reason behind the usage of different frequencies across the world?
The usage of different frequencies across the world is primarily due to historical and regional factors. Different power systems were developed independently in different parts of the world, and what worked best for one country may not necessarily work as well in another. Additionally, differences in power supply voltage, local climate, and other factors may also have played a role in determining the appropriate frequency to use.
