Why is the US standard 60Hz?
- dalke 11y ago"Sixty cycles has ever since been the standard for alternating current" That's incomplete. Los Angeles, for example, had 50 Hz power until the late 1940s. (For references: http://www.oldradio.com/archives/stations/LA/mtwilson3.htm http://www.oldradio.com/archives/stations/LA/mtwilson3.htm says "It is interesting to note that until early 1949 the Southern California Edison Company supplied 50 Hertz power to Mt. Wilson." and http://www.earlytelevision.org/national_schools_camera.html http://www.earlytelevision.org/national_schools_camera.html "It should be noted that Los Angeles used 50 Hz power at that time.")
