What are voltages inside resistors?

See also a related RG discussion and Codidact paper . By the mid-1990s, I had already developed my own philosophy about electronic circuits, and I decided it was time to share it with my colleagues. In the spring of 1997, I presented a series of three papers at the XXXII Scientific Conference on Communication, Electronic and Computer Systems at the Technical University of Sofia. The second of these was dedicated to my idea of visualizing circuit operation through interactive voltage diagrams . In this post, I will tell you about this venture of mine. Need to visualize voltage distribution Once visualized the voltages of the internal circuit points , we can go even further and "enter" inside resistors to visualize the voltages across the resistive film. This will allow us to see some interesting points (for example, virtual ground ), the operation of well-known electrical devices (potentiometer, resistive summer) and electronic circuits (inverting, non-inverting, differentia...
