I agree. People who have participated in this thread have mostly taken one of tho sides: The easy-going party has procured the analogies and ideas which helped me form an image of a process that I am content with at the moment. This was the purpose of my question in the first place...

In average, right? Not each and every one of them. Most of the motion is brownian motion, but it is biased in the direction of the current, so when you sum up all the vectors of velocity all that remains is drift speed.

Great, this is actually very visual :smile: One question though, maybe this goes without saying or you even said it but you used some terms I didn't understand :smile: If there is no current, free electrons are buzzing around in all directions. They have some kinetic energy depending on the...

Well, quantum mechanics is definitely on my list of things to learn, but I tought that I would first explain everything to myself in a "classical" way, and than upgrade that picture once I get some aquaintance with a quantum way of things (some time in the future). Would you suggest doing...

I don't think that I asked such a preposterous question, nor do I think that my understanding of physics is on such a low level for this problem. All I asked is how do you people imagine a diffrence in a high voltage flow of electrons, compared to a low voltage one. What difference would you...

Great analogy and great effort, Simon. So here's a picture I have so far: average kinetic energy of charged particles in a wire has little to do with voltage and current. It has more to do with temperature, probably. But what happens is when voltage is introduced, charged particles have a...

First, Simon: I was talking about the current, yes. "I" comes from "Intensity" and I tought that I would use the word Intensity for the current, and "Current" for adressing electricity. Sorry for confusing you, after reading your answers, I have realized that I messed up by using word...

So, how would you describe a "visual" difference between a state of high voltage - low intensity circuit, and low voltage - high intensity circuit (with same power)? let's just describe 3 situations: 1) voltage is zero. there is no flow of free electrons in the conductors. 2) voltage is...

Voltage is a property of a system or part of a system. It isn't a property of an electron

Dropping an object from a height starts a process of converting potential energy to kinetic energy. The bigger the drop, faster the ball will eventually go.THAT'S what I'm asking - what will the difference in potentials in a circuit convert to? What kind of energy? Because, by definition of...

Thank you for your responses! Yes! All right. Just help me wrap my mind around these three problems: 1) Does higher voltage mean electrons in a CIRCUIT accelerate faster (thus increasing their kinetic energy)? if so, 2) Does the overall (Brownian) speed of electrons increase...

So, I have a problem visualizing effect of voltage on the current in a circuit. Here goes: -Intensity (I) of a current is a ratio of charge traveling through a cross section of a conductor, and time. We can visualize it as a flow of water through a pipe: It is all about quantity of particles...
