Calculate the rms value of the following complex waveform:
V = 100. Sin (wt + 30) + 20. Sin (wt + 90) + 10. Sin (wt + 15)
NB. Vrms = sqrt(Edc2 + E12/2 + E22/2 + E32/2 + etc)
The solution is comprised of detailed calculations of RMS voltage of a complex waveform, whose components are not orthogonal to each other.
