How transistors REALLY work

[NewBeginner]

I understand what you are saying.
But please take a look at the following quote from the book: College Physics by Serway and Vuille (Part 4, Chapter 17):

In a common conductor such as copper, the current is due to the motion of negatively charged electrons, so the direction of the current is opposite the direction
of motion of the electrons. On the other hand, for a beam of positively charged protons in an accelerator, the current is in the same direction as the motion of the protons.
In some cases—gases and electrolytes, for example—the current is the result of the flows of both positive and negative charges. Moving charges, whether positive or negative, are referred to as charge carriers. In a metal, for example, the charge carriers are electrons.

Thank you

Perhaps good way to understand given scheme is to simulate one. For common collector amplifier you can simulate on:

What does this have to do with anything? You are not going to use ions to carry charge in a circuit. neither are you going to use electrolyte to make circuits.

You do realize you are on a electronics forum and not a chemistry forum?

These guys are too nice to call you on what appears to me to be trolling. You keep insisting on a physical fact that has no application whatever to electronics or electrical circuitry. Yes, you have pointed out many times that ions can carry charge. It has nothing to do with how transistors work. Let it rest.

So no batteries then.

So no batteries then.

At the risk of perpetuating a thread that has outlived its usefulness, batteries absolutely work with electrons. Batteries are electro-chemical systems and the whole field of chemistry itself can be summed up in one word: electrons. Chemical bonds and chemical reactions are all about electrons and orbitals and how they interact.

Take any given battery and the chemical reactions inside it cause electrons to be transferred from the positive electrode to the negative electrode. That is how voltage is produced between the terminals.

Rarely does electronics involve a stream of free electronics shooting down a path (for instance a CRT). Most of the time it's electrons moving around with the help of some carrier material.

Most of the time it's electrons moving around with the help of some carrier material.

like wires for instance ? made from metal ? or other conductors like carbon or metal oxide for resistors or sometimes semiconductors like silicon and germanium and others.

Why the hint of acrimony I think this thread is interesting. Just because it is an electronics forum doesn't mean we can't learn some physics or chemistry?

It isn't directed at anyone generally by the way

Off topic:

No it is not. I had not such intentions. Anyway, I think that these guys can speak for themselves and I don't think that they need an advocate to speak in their name  (and as I said before I greatly respect their knowledge; I have much to learn from them).

You keep insisting on a physical fact that has no application whatever to electronics or electrical circuitry

I think you are wrong about that. Also I believe that it is important to understand things as correctly as possible. I don't see how one can correctly understand electronics without physics and some chemistry. I may be wrong.

Let it rest.

Already did that. As you could observe I posted my previous reply one month ago.

Thank you

This lecture will answer it completely
