How much?!?
Grob's "Basic Electronics" is essentially "Electronics 101" - it is essentially beginners EE. It is a school textbook (I've seen it used in college syllabuses), so a current edition may or may not be cheap, depending on where you look. But an older edition will do just fine; the majority of the beginning topics covered have not changed much in the past 50 years.
It's been a while since I last looked at it, but it essentially starts out with what an electron is and builds from there, covering voltage, current, resistance, capacitance, the components that implement these concepts, how they are made, how they work (down to an electrochemical level - seriously), what a transistor is and how it works, relays, electromagnets, motors, etc, etc, etc. Toward the end of the edition I have, it starts going into 8-bit CPU TTL interfacing (kinda tells you the age of my edition); but that is really just a beginning - there's other books for that.
