That’s me! Definitely a slow work in progress… Thank you for the kind words of encouragement :)

Unless you’re doing specialized physics, in the electronics world we always talk in terms of current flow – never electron flow. Rather weird line from the site. My entire training and career have dealt with things from an electron flow perspective and it made understanding nearly every electronics concept easier. If you base your concept of electricity on positive current flow (remembering the words positive and neg…

Did you study electronics engineering or electrical engineering? In my experience the former (dealing with semiconductors and integrated circuits etc.) uses electron flow but the latter (designing power transmission and induction motors and transformers etc.) almost universally uses conventional current (then again they mostly deal with AC anyway so maybe it's less important.)

I've always struggled with electronics texts. Mostly because, rightly I'm sure, they discuss the individual components, or subsystems common to electronics: what's a capacitor, what's a resistor, what's an oscillator, what's an amplifier. But where they break down, for me, is they don't put it all together. It's like having your introduction to computers being nothing more than a book on data structures and algorithm…

This is where system modeling, differential equations, networks and control theory all come together to make sense of the “how and why” in using circuit components. That is years 2 and 3 in the EE curriculum—-at least it used to be.
