Average value or Mean value:
This is the average of the instantaneous values of an alternating quantity over one complete cycle of the a.c waveform. It is also known as Mean value.
To obtain the average, divide the period into ‘n’ equal intervals. At these individual intervals let the current are i1, i2, i3 …… in.
RMS Value:
Root Mean Square value of an alternating current is given by the steady D.C current, which produce the same heat as that produced by the alternating current in a given time and given resistance. To obtain the average, divide the period into ‘n’ equal intervals. At these individual intervals let the current are i1, i2, i3 …… in.
