Unformatted text preview: The peak value of the induced EMF is The AC voltage from power company refers to the rms value of the EMF, which is related to the peak EMF by The rotational angular speed ( ) determines the frequency ( f ) of the AC Therefore, an AC of 120 V at 60 Hz means which is generated with a rotational angular speed = 60 rev/s ( 120 rad/s ). NBA = 707 . 2 = = rms 2 = f V rms 120 =...
