Hello I'm a beginner (Second Semester) at Electronics Engineering.(adsbygoogle = window.adsbygoogle || []).push({});

In the attachment is the image of the filter rectifier circuit that I am analyzing. My professor has given us questions and their solutions but for my full wave filter rectifier analysis the numbers are not the same.

The analysis asks me three questions:

VDC, Vr, and ripple %

Formulas I use:

Vrp-p=(VLpeak/RL * period) / C (capacitor value).

VDC = VLpeak - Vrpeaktopeak/2

Vr(rms)=.577* Vrp-p/2

r=Vr(rms)/VDC

My halfwave filter answers are correct and these are the formulas I used.

But my fullwave/bridge answers go wrong. someone please do this question and see what answer they get.
