A time interval equal to 1/根号360 of the time required for one complete cycle of alternating current.Mechanical rotation

is often measured in degrees.360° constituting one complete revolution. In describing alteruating voltages and

currents,the time for one one complete cycle isconsidered to be equivalent to 360 electrical degrees(360°)or 2π

electrical radians 。 for example,if the frequency f is 60 cycles per second(60HZ),360°corresponds to 1/根号60 second

and 1 electrical degree to 1/根号21600 second。
