    Good explanation, but squaring a graph - say sin(x) - will not make the graph look the same with pure positive values, like the graph that appears around 3:32. Put sin^2(x) and |sin(x)| into a grapher and notice dy/dx differ by as much as 45 degrees near y=0. What you say, however, is precisely correct:)

    True RMS method is suitable for distorted waves???

  • @gerardvoughnfaust4167
    @gerardvoughnfaust4167 7 лет назад +1

    If taking the average RMS is peak mutiply by 0.707, what nmber will i multiply to get the true RMS from peak?

    • @harizirfananwarulhalim3146
      @harizirfananwarulhalim3146 5 лет назад

      The 0.707 multiplication value or division to the sqrt of 2 is only applicable to perfect sine wave form which gives a quick calculation or approximation to the RMS value. In the real world, wave forms has some distortion and you need to calculate based on the true RMS formula as per described in the video

    vp is not the effective voltage while vrms is right ???? so we need to find out rms value ???

    • @AEMCInstruments
      @AEMCInstruments  4 года назад

      Correct. RMS is needed to calculate the effective voltage, not the peak.

    what is the need of Rms value? still it is not cleared to me. please.

    • @AEMCInstruments
      @AEMCInstruments  7 лет назад +2

      AC is alternating current. It performs work when the voltage is positive *and* negative. This means that the standard mathematical average is an invalid measure of voltage or current. Instead, RMS is used.
      With RMS the quantity is first squared, to "flip" the negative to positive. It is then integrated, and finally, the square root is taken to remove the error caused by squaring.

    Still doesn't help me understand: why is RMS different from simple average of absolute value of signal readings.

      You want to get the power equivalent for a constant voltage. You are constrained by the equations for power.

    Looks like he quared half the value using either half,but said we square the value.AC is a directional power by convention from negative to positive.AC has power coming and going it will turn a motor both ways.As students we need a different way of understanding electricity than convention teaches.It may be fine for the mathematics to say we have a negative voltage but the power is not negative and this leads to confusion.PS I am probably wrong as I am not versed in electronic or physics but this whole convention thing sucks confusion like a vacuum.
