Thanks for your helpful comment! I was also struggling with the bad circuits voltage divider.

  Sure thing! One of the things that helps me sometimes is re-arranging things visually. A real divider: Input o----vvvvv----o-------------o Output | | Z Z Z | | o Ground The bad one: Input o-------------o----vvvvv----o Output | | Z Z Z | | o Ground Looking at it this way, it might be a bit easier to see that in the good circuit, both resistors can be in a Kirchoff voltage loop that includes the input, while in the bad one they can't. (Edit: it appears I don't understand linebreaks on HN, so things are gonna appear garbled until I fix it.) (Edit 2: Fixed.)
