>is there a book for the theory behind all this stuff?

It would be "books", and I like how you want to learn everything. That's a good goal when you are young and have time. If you can go to the book store at a good engineering university that has Electrical Engineering, look at the textbooks for first and second year, and look in them to see the level of detail. Things like motors are not covered well in university, in my experience.

Or, go to wikipedia and other sites on the internet and read a topic, and don't go on until you actually understand what it is saying. buy an oscilloscope and start building circuits and try to figure out why the subtle things happen, and how to read a spec sheet to see that those subtle things are sometimes described and sometimes they aren't. Look at manufacturer's sites for application notes; the better ones are crammed with information. Here's an example of one that you might spend weeks studying and still not learn everything that it can teach you: http://www.analog.com/media/en/technical-documentation/application-notes/an47fa.pdf

And this is just me, but I would steer clear of youtube. I don't think you can learn things like electronics or programming by watching videos.
