Hallo!
I have this problem with my bridge I'm trying to convert AC voltage to DC generated out of a small 12V/DC motor.
I generated almost 8.4V/AC. I'd like to convert it using my bridge,so I made a simple rectifier using this schematic.
Added a 1000uF capacitor at 16 volts to smooth out the DC output and I followed this formula to calculate the expected voltage Vin/AC x 1.4 = Vout/DC.
And here's the result:

*Here's the problem... I made the "full wave bridge rectifier" and tested out the product I had 8.4V/AC in and I got almost 3.4 Volts DC out, I thought the voltage would be 11.76V/DC than "3.4" according to that smoothing formula "V/ACin x 1.4 = V/DCout".
What do you all think is the problem?
I used another capacitor 4700uF at 16 volts and the output was almost 2.6V/DC... What am I doing wrong? Or is it just normal?
lets say even if there was a voltage drop I thought it would be some simple number not that much of a drop .
Here are some pictures so you guys can see what I'm dealing with.
