Step 1 : Perform Sampling Current case we take half of sine wave. We can also take another half of sine wave Step 2 : Square all the value Step 3: Mean/Average the Squared value Step 4 : Square Root the value from step 3 Done! You've got the RMS Value.  AC RMS equivalent to DC Fast Track -> RMS Value = 0.707 * V Max    - Mostly applicable for pure sine wave Sources :  https://www.youtube.com/watch?v=Ynv_C3N0fPk
