How does a voltage doubler work?

  1. Dec 5, 2015 #1
    Hi, I have this voltage doubler circuit that we built in lab:

    We're told that, with the jumper inserted, the output voltage is about twice as great as without the jumper. We didn't need to prove this theoretically, but for my own curiosity, I was wondering if someone could give a clear, thorough explanation of why this works. When I search online, I see circuits that are similar but not quite the same, and kind of short answers that I don't quite understand. Thanks!
