AC/DC. Ahhh...great band. But here we're talking about electrical currents.

What does it mean? AC = alternating current (sloshes back and forth), DC = direct current (goes one way).

If you think in terms of pressure the resistance becomes back pressure...

I love your lectures, but this is a bad analogy, changing the voltage, current, or resistance doesnt' reflect in the system the same way it reflects in the analogy.

When choosing an analogy make sure the variables when changed still accuratly reflect the system they are analogies for. Otherwise this causes more confusion when the student tries to use this analogy in the future to explain a similar system with changing/different variables.

I think it would be less confusing to simply say, electrons move from a high potential energy state (all bunched up) to a low potential energy state (equally spread out across the system) when given a path to flow through releasing that pent up energy they had, sitting within eachother's electrical fields.

Then you could say, *similar* to water flowing downstram releasing gravitational potential energy given a path to flow. (But even then, this analogy can still cause confusion, because the electrons dont "all" flow to the negative terminal (like the water does), they stop at an electrical equilibrium spread out everywhere)

In the end make sure the analogy causes more clarity than confusion. Bad analogies caused me months-years of headache when I was figuring this stuff out. Or note* the analogy's limitations.
