The average value of an alternating quantity is defined as the arithmetic mean of all the values over one complete cycle.

Consider a symmetrical sinusoidal waveform in this case average value is over a complete cycle is 0. Hence, the average value is obtained over a half cycle.

$Iang = i1 + i2 + i3 + …….. im/ m$

∴ the average value of I (t) over specified internal t1 to t2 is expressed

$Iang = 1/ t2- t1 t2ʃ t1 i(t)$ at
