Straight Forward Answers

[Rich Grise, but drunk]

Does anyone else approach it as simple hydraulics or plumbing? I'm
somewhat teaching myself and I think in those terms, current being the
flow of water and voltage being water pressure. A resistor is like a
constrictive valve (bending a garden hose), a capacitor is like a water
tower, a diode is like a butterfly valve, a transistor is like a faucet,
etc. This type of thinking has its downfalls but has worked enough to
keep me from giving up. I'll read the chapter on transistors in five
different books and they all sound like rocket science. I'll finally be in
the company of someone with a working knowledge of transistors and he can
explain it in 10 minutes. Now why can't any of the expert authors do that?
This group has been VERY helpful to me several times, members patient with
my "dumb" questions and DO give straight answers. A best seller would be a
collaborative book authored by sci.electronics.basics!

I'm proud of you for investigating this stuff on your own impetus - I like
the "water pipe" model, except when it comes to dealing with short or open
circuits - with water pipe, the effects are the opposite from electrical
wires!

And a capacitor isn't a tower, it's a tank with an elastic baffle in the
middle. And an inductor is a flywheel with a positive-displacement
pump/turbine, like a vane pump or gear pump.

But I fear that there's no financial incentive for anyone to write
anything new these days, with all of the books in the libraries, and,
well, the whole freakin' internet at your fingertips!

Hope This Helps!

Actually, I like to explain inductors in the water model as long
(coiled?) pipe, where the inductive effect is provided by the inertia
of the water. It resists rapid changes in motion, and once you get
the large mass of water moving, inertia wants to keep it moving.
