Wrangling Electrons

Computers are great adding machines. They’re also great at comparing things that usually don’t work well together. Jim Campbell has a nice animation about this. We can get away from the mouse, monitor, keyboard (and now ubiquitous touchscreen) to think differently about these machines we use all the time.

At the end of the day, all we’re doing here is wrangling electrons. They want to move from a place of higher potential energy to a place of lower potential energy (we call this ground). The bus falling off the side of a cliff metaphor is generally a good idea of how we can think of these things moving through a circuit.
