I've been following this course (to refresh my informal knowledge of electronics, which I haven't touched since I discovered it was way cheaper to write broken code than build a broken circuit back in my teens) and it's pretty good. I like how they mix the theory with practical experiments showing it in practice. I don't recommend the Kindle version though, the formatting is really lacking.
