I would suggest things that use the hydraulics analogy, like this: https://ece.uwaterloo.ca/~dwharder/Analogy/
When you get to active (transistors, diodes etc) devices don't spend much time trying to figure out the physics of these things just use the equations and keep it simple. Just as when you're cooking eggs in the morning it doesn't help much to understand prospecting, mining and metallurgy to use the frying pan.
