It's "magic" use Abracadabra or Alakazam when trying to explain it !
Hand gestures are a must ! Presentation is everything !

Well, that seems simple enough. Let me make sure I've got it right:Perhaps the answer you are seeking is the electron concentration at wire B is higher than that at wire A.
If it's not a physical difference, what kind of difference is it? I always thought an ion was physically different from a non-ion specifically because it had a different number of electrons.Wire A and wire B are practically equivalent. We do not consider charge concentration as a physical difference.
Thank You.Then I sincerely suggest that you teach some other subject and not electricity and electronics.
Just because you remove an electron does not make the atom or molecule an ion.If it's not a physical difference, what kind of difference is it? I always thought an ion was physically different from a non-ion specifically because it had a different number of electrons.
Okay, fine. I'd prefer to stick to the original question, if you don't mind. Is the following correct?Just because you remove an electron does not make the atom or molecule an ion.
We are referring to the movement of electrons in metallic conductors. Electric current in a conductor is the effect of free electrons which you can imagine as a cloud. The atoms of the metal do not become ions.
Maybe this will help.Okay, then what accounts for the potential difference between the capacitor's anode and cathode? In other words, what is physically different about the capacitor's anode and cathode when the capacitor is charged to 100 volts?
Let me see if I understand what you're saying. Let's say I have two similar books, A and B, sitting on a table. When I lift book A above the table it is now at a different gravitational potential than book B, but it remains physically unchanged. Likewise, when I connect wires A and B to opposite ends of the charged capacitor, wire A is now at a different electrical potential than wire B, but it remains physically unchanged. The field of which you speak is therefore, at least in some respects, the electrical analog of gravity. Yes?There is no difference between the two wires. The difference is that they are at different electric potentials. That difference is caused by the electric field between the two plates of the capacitor.
Because the reading on a voltmeter connected across the wires changes throughout the discharge period. So something must be changing in or on or around those wires.Why do you assume the wires change?
I agree, the pipes themselves don't change, but there is a physical change in the water in the pipes when the pressure is increased (eg, the molecules are more tightly packed, or are more energetic due to heating, etc). So I thought there might be a physical change in the atomic configuration of the the wires when the electrical potential is increased (eg, "more free electrons" or "free electrons vibrating more energetically" or "free electrons pulled further away from protons in the wire" or something like that).Water pipes don't change depending on the pressure or water flow. (That is assuming it is a good pipe, and below the bursting pressure. Water analogies are not perfect!)
Yes, but the increase in heat is an effect, not a cause. As I understand it, the cause is friction between the moving free electrons and the other relatively stationary atoms in the wires.The only change I can think of for the wire could be some heating depending on the current.
Do you mean the position of the wires, or the position of the free electrons in the wires? Are you thinking of the field as a cause or an effect?And maybe their position due to the magnetic field produced.
NO! Gravity is a function of MASS/DISTANCE^2 and electric fields have no relationship to MASS! How many left-handled angels are we up to now?electrical analog of gravity. Yes?
The wires thenselves.Do you mean the position of the wires, or the position of the free electrons in the wires? Are you thinking of the field as a cause or an effect?
You teach science?!?! Heat is a measurement of released energy due to the collision of particles. Too many angels around here, I'm going back under my rock to take a nap.Yes, but the increase in heat is an effect, not a cause. As I understand it, the cause is friction between the moving free electrons and the other relatively stationary atoms in the wires.
