    Great video thanks so much. I have a couple questions. At 10:00 can I assume you doubled the capacity of the bottom capacitor (as per your diagrams)? And that you only had one protection circuit on the top capacitor?

    Because the zener is not providing enough current to the bottom large capacitor, too much is still going to the top one. That results in the top (smaller) cap having an over voltage. Is that correct?

      1. Yes
      2. The zener has no clear cutoff voltage. Therefore, it allows voltages above the 2.7 volt (because its resistance is too high).
