I had read that average value of current must be calculated for half time period. For example if we apply it for a sine value full time period then its value becomes zero. But for any arbritrary graph which doesn't have shape similar above and below x axis. I mean that they have different kind of shape for half timperiod and for another half, (Periodic function/graph) Then by calculating avg. Value for current (calculation for half timeperiod) don't we lose the real meaning of average. Should we include that negative part of waveform to our average I , by taking modulus?
