I've been recently learning all about hobby electronics recently (circuit design, microcontrollers, basic components so far), so I want to give a beginner's perspective, and honestly this water pressure /flow analogy is actually really distracting and misleading as soon as you get past the basics of circuits and components.
If you're an educator please reconsider using these analogies that fall apart later on becuase in more complex concepts but the analogy may stick on in your students head when it doesn't apply. Or at least heavily stress that these are analogies and not to expect that this "water circuit" analogy will hold forever.

- shadowgovt 5y agoI don't know how hard it is to find these days, but I stumbled across a book called "There are no elections" ages ago that I found very helpful. As a student of American high schools familiar with both the water analogy and the basic electron flow theory we get in school, that book does a good job of upending both by presenting a sort of third model that, while tongue-in-cheek, fits the observations the first two models explain. Then it's sort of goes on to show how those models are all lacking because there are other things we know about electricity that don't fit any of them.
