Earlier quoted context omitted.

I just want to weigh in and say that fantastic as _The Art of Electronics_ is, it is _not_ geared for learning about electricity and electric circuits. The first 13-ish pages (3rd edition) deals with electricity and then quickly moves on to signals, electronics and everything else needed to _develop_ electronic systems.

I think you're wrong, mainly because learning how to develop electronic systems is, in my opinion (and also in the opinion of the authors of that book), the best way to learn how electricity actually works.

There is no reason to be so absolute about it. I'm not saying it is a bad book or that you should read "Field and Wave Electromagnetics" before you ever dare touch a multimeter.

As an example of my reasoning. AoE and the Arduino starter kit cost roughly the same in my country. They are of course not comparable, but I'd would definitely recommend the latter to someone completely new to electronics, exactly because the latter gives the tools for experimenting.

I enjoyed "There are No Electrons: Electronics for Earthlings" by Kenn Amdahl. It's a light hearted take in the form of a silly story, but it explains things surprisingly well.

Guess I should add that it covers the basics of electricity and the basics of electronics.

I got a lot from the articles on amasci.com by Bill Beaty. He's done a lot of experimenting, reading, and thinking about this stuff and how to explain it. And is a gifted communicator. Articles on Electricity http://amasci.com/ele-edu.html Great essays on understanding electricity, current, voltage, capacitors, transistors, batteries, static electricity etc etc, and popular misconceptions.

Yes, he is quite a wonderful teacher.

Try "Code: The Hidden Language of Computer Hardware and Software." It provides a very simple introduction to electricity. Beyond that, it's just a great introductory book on computing.

= Geared a little more towards mechanical engineering, but Jeremy Fielding on YouTube has helped me understand some of the concepts with examples rather than textbooks. https://m.youtube.com/channel/UC_SLthyNX_ivd-dmsFgmJVg

= For straight up electric concepts, I’d look at the Georgia Institute of Technology stuff on Coursera. “Introduction to Engineering Mechanics” and “Linear Circuits 1” were helpful.

Walter Lewin's electromagnetism course from MIT [0]. These lectures completely transformed my understanding of physics. He mixes practical demonstration with a rigorous mathematical underpinning in a way that doesn't over simplify things.
