So I am testing my PZT Piezoelectric material's Voltage output across a Capacitor of 1000uF after converting AC to DC using an Oscilloscope. Oscilloscope model: Gwinstek GDS-2102.
The diagram is my model for testing the Voltage across the capacitor.
I am trying to see the output across the capacitor when I tap the PZT. this follwing waveform is from my AC to DC converter.
So as you can see, my AC to DC works perfectly. But now the Voltage across the capacitor is shown in the next waveform.
So as you can see it is not a DC rectified waveform.
Could anyone please let me know what is going on here?
