Whatever you think you know about resistance, I want you to completely forget it—especially the water pipe analogy. In this video (Resistors Part 1), I rebuild resistance from the ground up the way I wish it had been taught to me, even back when I was a senior electrical engineer at Intel and later a university professor. Resistance isn’t a cute metaphor; it’s literally how easy or difficult you make it for electrons to move through a material, and that framing changes how you think about real circuits. I walk through what’s physically happening: electrons carry negative charge, they repel each other, and when you apply an electric field (a voltage potential difference), they respond by moving. But they don’t “zip” through copper at the speed of light—electron drift velocity is slow (millimeters per second). What moves fast is the electromagnetic field. The key is collisions: electrons bump into the material lattice and each other, and that kinetic energy gets dissipated as heat that doesn’t return to the system. That’s the essence of resistance, and it’s the foundation for designing industry-ready electronics instead of memorizing surface-level rules.
