I originally learned electricity from Isaac Asimov's understanding physics, volume 2 when I was 13(?). I don't remember the details, but it clearly worked and helped me in all future education.

If you want to try and learn some basics, and then try apply them, both AoE (mentioned already by pjc50) and "Practical Electronics for Inventors" are good choices.

The latter is much more affordable than AoE.
