i have come across two different formulas for ripple factor:(adsbygoogle = window.adsbygoogle || []).push({});

One is r= (Vrpp/Vdc), where Vdc is the dc voltage of the output and Vrpp is the peak to peak ripple voltage. My professor uses this formula and I have also seen it being used in basic electronics by Floyd

Another one is r= Vrms/Vdc from electronics by boylestad. Are these correct?

Is it possible to show that they are equivalent. Please help. Thanks in advance
