I found 2 equation for calculating the peak to peak ripple voltage,(adsbygoogle = window.adsbygoogle || []).push({});

this one is the common one i see,

V_{ripple p-p}= I / 2fC

And i also see this one in my book, but can't really find any other source use this formula,

V_{ripple p-p}= V_{rect}/ fR_{L}C

V_{rect}is the peak voltage of unfiltered voltage

f is frequency,

C is capacitance

R_{L}is the load voltage

What is the difference between these two formula? Are they really for counting the same parameter?
