How pull-up resistors really work

There are several explanations of pull-up resistors that I find gloss too much over the details. After some researching and doing circuit analysis to clear up how they work (theoretically), I wrote a blog post. Maybe it's useful to others as well.

This post uses quite some formulas, so I'll provide a link instead:

I edited it over many days, adding images and changing the wording. If there is a mistake now, please let me know.
