This guide has been around since the early 00's. I read it, start to finish (well, some chapters weren't finished back then :) when I was a teenager and it got me started with electronic circuits.
I ended up becoming an electrical engineer and credit this site significantly for giving me the courage to choose EE in uni.
The guide does an excellent job of building up knowledge without assuming any prior knowledge - just what a curious 15 years needed to get started.
dspguide.com is another great resource and thought me Fourier transform when I barely knew what cos() and sin() were.
I wish I had these resources when I was in school. I was studying EE back in the late '80s. I had a textbook with maybe two worked out examples for each concept. The answers to the odd-numbered homework problems were in the back, but just as a number. So if I worked out a long problem and got, say, 5 as an answer, and the answer in the back was, say, -5, I had no real way of knowing if I made a mistake somewhere, or if the answer in the back of the book was incorrect. Working in groups was discouraged as a kind of cheating because you were supposed to do your own work. The professors weren't that interested in teaching because they felt they were there more to rank us. And the teaching assistants were mostly foreign-born with limited spoken English skills.
