Where do all the electrons go?

It's funny. Scientifically, evolution is understood from top to bottom. We know almost everything about it. I don't think there is a scientific concept as well understood. But it is controversial.

Gravity, magnetism, and electricity. We can describe them and use them, but we don't understand them. Why aren't the school boards outraged about teaching them? They contradict the Bible, too. Joshua 10:13 Isaiah 38:8

As for dust bunnies, it's easy. God makes them.

Sure, almost all electronics is analyzed using the (incorrect) positive current carrier model. The math works, so why not. Engineers also understand (or should) that this is only a useful model at the macro scale.

No, nothing has been rewritten, at least in the last fifty years. They are very different concepts. "Electrons" are the (majority) carriers of electrical current in conductors and "holes" are the carriers in insulators. Semiconductors are interesting in that the majority carrier can be either, depending on the material. They're "semi" because they don't act like either conductors or insulators, rather somewhere inbetween. Also interesting, in semiconductors, is that the minority carrier gets interesting.

Holes vs. excess electrons is a semiconductor discussion at the molecular level and should not even be in this thread (IMHO).

Conventional current flow (which was arbitrarily chosen to go from + to - before anyone understood it) vs. electron flow is what is being discussed here. You could redefine current to be the opposite way, but there isn't really any reason to do that.

Finally, lumping electricity into the list of forces we don't understand isn't correct. I think electricity is fully understood these day. It is not one of the fundamental forces that are still being analyzed at a subatomic level to this day.

A semiconductor is nothing more than a device to control the flow of electrons/holes. Which is the subject of this thread and therefore on topic. Which is also probably way more than the average reader cares to know.

No, it is a class of materials, from which the devices got their name.

The thread itself is off-topic, but only the lowest form of pond-scum plays netkop.

You can kill the thread anytime.

The electrons that flow in your example are not from the wire, but from the power source. It is a very good question,I bet it would change any professors quick class on electron theory to "Stick with the Course or please leave the classroom" lol.

Usenet/Internet Warning: Though the Infernal machine "PROTEUS" officially shut itself down at

2:02 AM (Mountain Time) several world wide web systems in undisclosed locations in the US and abroad still have bugs and unrecognized devices it cleverly installed that I still need to remove. I have confirmed the above and taken possession of it's now near dysfunctional com systems and am working on all the problematics it's demise has left us with with the a team of worldwide software and computer experts. Thank you. THE MANAGEMENT (there-at)
