average value of sine wave
rms is root means square (average of the sine wave) and peak value is the top of the sine wave ANSWERis root means square and it is not AVERAGE the average is .639 of RMS AN â¦ D PEAK VOLTAGE IS 1.41 X rms. Find it in any book   Comment The average value of a complete sine wave is zero. The figure of 0.639 Vmax or 0.639 Imax is the average over half its wavelength. The rms-value of a sine wave is 0.707 Vmax or 0.707 Imax.
