1- Is root mean square just the average amplitude of a wave
2- Why isn't the RMS of a sine wave 2/pi?

might have more luck in the physics chan

Yes, but I already have a running question there.

ahh, word well I was just letting you know just in case you didn't know. I'm sure someone here can help eventually...

anonymous · Answer

I kinda forgotten this topics.. but I remembered that V(RMS) is the average amplitude of the wave

anonymous · Answer

VRMS = Root 2 / V peak i think

|dw:1345924934616:dw| Surely it should be$$\frac{\int\limits_{0}^{\pi}Asinx dx}{\pi}$$, but http://en.wikipedia.org/wiki/Root_mean_square#RMS_of_common_waveforms disagrees. My method works out to 2A/pi, not A/sqrt2
