I have four capacitors connected in series and I will apply voltage over them.
The voltage is generated from a DC-motor, and I want to make sure it does not rise above 9V. What is the best way of doing this?
My initial thought was to use a 9V voltage regulator. But as I understand it, if I generate less than 9V (which I will likely do) I will end up losing some voltage even though I don't want to (voltage drop?).
What are some other ways I could limit the voltage?
