Average Voltage of a Sinusoidal AC Waveform
The average value of a whole sinusoidal waveform over one complete cycle is zero as the two halves cancel each other out, so the average value is taken over half a cycle. The average value of a sine wave of voltage or current is 0.637 times the peak value, (Vp or Ip. This mathematical relationship between the average values applies to both AC ...

Why 'sine' wave of alternating current?
The sine wave is a consequence of the way the AC is produced. When driving a generator you simply cannot directly create DC.
