Distance? Just how fast do you think this "Electricity" is moving?


http://en.wikipedia.org/wiki/Speed_of_electricity

Taking into consideration how small electrons are, the difference between a transistor's "0.1mm" distance and a vacuum tube's ~3cm distance is astronomically different, like the difference between how close the moon is to Earth and how close the sun is to Earth. Sure, if we assume that electricity is flowing at roughly 80% of the speed of light, the difference shouldn't be noticeable, but I wasn't talking about how fast electricity propagates so much as I was talking about pressure gradients.


I think you said it best:

so again, I suggest you read and understand:

http://www.aikenamps.com/Sag.html

or do your own google search, I'm sure there are plenty of valid explanations for
what produces sag. I'll add though, that to understand it you must get familiar with
the terms, voltage, current, resistance, etc that are used in physical rather than
metaphysical explanations of circuits.
