If 50 Hz is more efficient why we use 60 Hz?
I was wondering why we use 60 Hz instead of the more efficient 50 Hz frequency?
The reason for using 60 Hz as the standard frequency in the United States is because it was chosen back in the early 1900s as a compromise between the existing 50 Hz systems in Europe and the 133 Hz systems used in some parts of the US.
