Real devices have real properties. Balloons do so catastrophically as do most electrical capacitors. OK, enough of that, you get the idea pneumatics are an excellent analogy of electronics. The flow of electrons is surprisingly similar to the flow of air. This is because they are really both fluids.
Air is the fluid of gas molecules slamming into one another trying to spread out.
Electrons are the same thing, they are also bouncing around trying to get away from one another. This is why it is not so surprising that they behave so similarly. Now, like any analogy, it can be taken too far. You can not start talking about pneumatic inductance without creating a real contrivance. There s just some things that are different about electrons and can t be forced into a model.
