by

1 Answer

Answer :

1. RMS value:- For an alternating current, the RMS value is defined as that value of steady current (DC) which produces the same heat or power as is produced by the alternating current during the same time under the same conditions. Irms = 0.707 Imax 

2. Average value:- The average value is defined as “the average of all instantaneous values during one alternation. 

Or 

Average value:-average value is that value is obtained by averaging all the instantaneous values of its wave over a period of half cycle. Iav=0.637 Imax
