If nothing else, it may help them understand where to seek solutions for the common problems they encounter. I started learning Electronics at a fairly young age using undergraduate level textbooks that I found lying around. The need for and relationships between concepts in calculus, logarithms and trigonometry were a recurrent problem for me.

PS: If anybody is wondering, those books were from an earlier generation engineer. They were very interesting, to say the least. All the circuits (amplifiers, rectifiers, oscillators, multivibrators, mixers, various RF Txr and Rxr designs, etc) were using vacuum tubes! Diodes, triodes, pentodes, thyratrons, magnetrons, TWTs, etc were used liberally in them. It had a description of an early form of the Instrumental Landing System (ILS). There were also descriptions of some early generation semiconductor devices and their similarity to vacuum tubes. I don't think ICs were in much use back then, because the book had no mentions about them.

I used to spend hours at a time with those books when I was a child. Later I graduated in Electronics engineering and went on to work on the avionics for a satellite launcher. Vacuum tubes were museum pieces by the time I was born. But I was the only one in my undergraduate class who had seen or knew anything about vacuum tubes, when we had lessons on CRTs, magnetrons, etc. I can't stress how deeply those books influenced my education and career. Sweet memories!

Traditional books benefit from having an editor who (ideally) asks questions like "who are you writing for", "what's the best order to introduce ideas", and "how much detail is enough". If you don't ask these questions, you often end up getting too deep into the weeds or jumping back and forth between ideas in ways that can be difficult to follow. To give you a specific example, the guide spends a lot of time on some of the more obscure theories in DC network analysis before even defining what a battery is, capacitors and inductors are explained in the DC section by focusing on their AC characteristics, there is a ton of unnecessary quantum physics trivia ahead of explaining what a diode is, discussion of op-amps kicks off with an odd reference to calculus, etc.

Again, I don't mean that as a criticism, it's just that (properly edited) books have their merits.

It had a wonderful kit where you would use screws in a board so you could see every wire path. Much easier to explain than modern breadboards
