RMS Voltage

  1. Jun 23, 2007 #1
    I have a question about RMS voltage. I know Vrms is Vpeak/sqrt(2) if the sine wave is centered around 0V, but what if the voltage has a DC offset? Shouldn't this mean the RMS voltage is more?

    Sure. It's the square root of the sum of the squares of DC and AC.
