Alternating voltage/rms voltage

[lavster]

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=V_osinwt, how do you work out V₀? is it the rms voltage?

cheers

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