The ratio of the RMS value of a sine wave to its peak value is 1.414 (or the RMS is 0.707 x the peak).@rjenkinsgb How you find 0.707 v please
play with the numbers a bit more and you'll realize that 1/1.424 is 0.707 or 70%. And, therefore, rms is 70% of peak.The ratio of the RMS value of a sine wave to its peak value is 1.414 (or the RMS is 0.707 x the peak).
0.5V x 1.414 = 0.707, as it happens.
It's nothing to do with the square of the voltage, if the other answer seems to imply that.
And Sheldon Copper from The Big Bang Theory was completely wrong about the best number being 73The best number is, 0.5^0.5. Or, as crutschow approximates,My virtual HP-42s gives 0.707106781186547524400844362104849.
ok, but are you trying to...
