Help me understand how does electricity travels inside a wire.

Electrons don't actually move, they are energized so the matter itself becomes energized in a way that creates imbalance. Magnets.

>>8724915
yeah, magnets. look up Faraday's work, its pretty easy stuff.

They don't move that much, but they are very tightly compacted and push against one another.

As an addendum, each electron is both repelled and propelled by the electrons ahead and behind (in 1-space) of it, so all you care about is the field attracting/repelling it.

So basically when they say "the point of high potential" do they refer specifically to "many electrons in one place waiting to burst" or its something more abstract?

you need to look up a thing called drift velocity
and perhaps skin effect

>Free electrons in a conductor follow a random path. Without the presence of an electric field, the electrons have no net velocity. When a DC voltage is applied, the electron drift velocity will increase in speed proportionally to the strength of the electric field. The drift velocity is on the order of millimeters per hour. AC voltages cause no net movement; the electrons oscillate back and forth in response to the alternating electric field (over a distance of a few micrometers)

High potential is a big slope, so imagine a load of electrons skidding down a steep slope, very quickly at that.

>>8724979
But they're not right? They move very little and they all have the same elementary charge each and thats why I'm confused about how is high point even made. Are they actually pushed to high point by external field so there is actual physical lack of electrons on the other end?

>>8724978
I get how they move I think I dont get how is the actual field "transfere" over electrons who dont move much. How do they pass the energy? Same like air with sound waves? Is it same analogy?

>>8724993
Exactly, a negative field is created by a net negative charge.
[eqn]
\vec{E} = \frac{Q}{4\pi \epsilon_{0}r^{2}}\hat{r}
[/eqn]
There is a physical lack of electrons at a positive charge.

>not \textbf for vector fields


engineer detected, lol

Wut? Seven years of secondary school and an A Level in Physics, and electrons don't flow? Dafuq is electricity then? What is happening when the red wire from the battery touches the light bulb and makes a circuit?

>>8724993
Just to clarify a point that wasn't made in the thread, the electrons DO move, A potential is a bunch of electrons contrasted with a large absence of electrons. The electrons move towards the lack of electrons due to a force that is proportional to the charge (lack or amount of electrons present at the point)
There is a net electric force such that the electrons move.

The electrons move enough in one atom to trigger the next atom. They don't leave their atom. Even a electric spark isn't electricity, it is recombination.

>A potential is a bunch of electrons contrasted with a large absence of electrons
How can there be actual absence of electrons? they literally leave their atoms and group in one place thus making high potential??

Thank you for the thread OP, I was quite confused about this as well.

>>8727079
There simply cannot be a way that you are now less confused having read this thread.

If I remember correctly they move at a rate of millimeters per hour.
