Alternating voltage/rms voltage

  1. Apr 22, 2010 #1
    hi, this is probably really obv but say you had an alternating voltage that has peak voltage 50kV and a frequency of 400 hz and you want to write the voltage as V=Vosinwt, how do you work out V0? is it the rms voltage?

    Vo is the peak voltage.
    The rms voltage is Vo/√2 [Vo x 0.707 approx]
