# How to use measured values to obtain an experimental ripple factor for a full wave bridge rectifier with no filter

Hello this is my first post. This is my thought process:

I can use the following equations to calculate the theoretical ripple factor for a full wave rectifier:

Through simplifying, it can be rearranged to give a constant ripple factor of 0.483.

Now, I built a said full wave bridge rectifier with no filters with a breadboard, the input AC source is 2vpp (amplitude of 1v) @ 500 Hz, resistor is 1kOhm, and 4 diodes. This is the circuit:

Using an oscilloscope, I have measured the signals:

How can I use my measured values to calculate an experimental ripple factor value? It does not seem as simple as doing Ripple Factor (Rf) = Vac/Vdc. If I do 1/2.01 this gives a value close to but it does not make sense that Vac would be 1v and Vdc would be 2.01v? I have tried consulting other info online but it all seems to be theoretical.

I feel like I am missing something crucial as I have spent a lot of time trying to figure this out and have not made any progress. I'm at the point wondering if there is no such thing as an experimental ripple factor and it is just always constant? Any help is greatly appreciated.
