I'm trying to figure out how to use a simple oscilloscope to show me a curve so I can determine if a capacitor is working as it should or not (and then calculate its Farad rating). First I want to make sure I have set the non-oscilloscope portion up correctly. My goal was to use a switch that discharges the cap in one position and applies power to the cap in another position, which in theory will trigger the oscilloscope when the voltage becomes non-zero. Can anyone verify that my schematic will do that? Does the voltage on the hot ("+") end of the cap rise as the cap charges and then stay constant when it is fully charged?
