All I can say is some people need to read "27–5 Examples of energy flow" of "Field Energy and Field Momentum" from "The Feynman Lectures on Physics".
https://www.feynmanlectures.caltech.edu/II_27.html - I think he is a well known Smoothbrained YouTuber who preached to kids, or something like that.
Regarding energy flow in resistors:
As another example, we ask what happens in a piece of resistance wire when it is carrying a current. Since the wire has resistance, there is an electric field along it, driving the current.
...
There is a flow of energy into the wire all around. It is, of course, equal to the energy being lost in the wire in the form of heat. So our “crazy” theory says that the electrons are getting their energy to generate heat because of the energy flowing into the wire from the field outside. Intuition would seem to tell us that the electrons get their energy from being pushed along the wire, so the energy should be flowing down (or up) along the wire. But the theory says that the electrons are really being pushed by an electric field, which has come from some charges very far away, and that the electrons get their energy for generating heat from these fields. The energy somehow flows from the distant charges into a wide area of space and then inward to the wire.
On energy flow in a charging capacitor:
Now we take another example. Here is a rather curious one. We look at the energy flow in a capacitor that we are charging slowly. (We don’t want frequencies so high that the capacitor is beginning to look like a resonant cavity, but we don’t want dc either.) Suppose we use a circular parallel plate capacitor of our usual kind, as shown in Fig. 27–3. There is a nearly uniform electric field inside which is changing with time. At any instant the total electromagnetic energy inside is u times the volume.
... snip out the maths ...
So there must be a flow of energy into that volume from somewhere. Of course you know that it must come in on the charging wires—not at all! It can’t enter the space between the plates from that direction, because E is perpendicular to the plates; E×B must be parallel to the plates.
... snip out more maths...
The energy isn’t actually coming down the wires, but from the space surrounding the capacitor.
... snip out more maths ...
But it tells us a peculiar thing: that when we are charging a capacitor, the energy is not coming down the wires; it is coming in through the edges of the gap. That’s what this theory says!

All Richard Feynman was saying in the first quote is that you need to maintain a potential difference provided by a power source in order to have any electrical current.
And that electromagnetic fields around wires contain energy, because they are directly connected to the movement of electrons that also contain energy.
The second quote Is Richard saying that a flow of extra electrons into one side of the capacitor will generate a negative electrostatic field that traverses the dielectric gap to repel electrons out of the other capacitor plate.
Giving it a positive charge due to a depletion of electrons.
He is trying to emphasize the importance of fields in electrical phenomenon.
An electrical signal in a good conductor unfortunately doesn't travel anywhere near the speed of light because.... The energy is actually being transmitted by particles with mass.... they are called electrons.
If electrical signals were all transmitted primarily by electromagnetic fields or waves we would expect a light-speed transmission of signals in wires.
Richard Feynman would agree with this. Notice how many times he emphasizes that it is "nuts" and a "theory". He said it four times on that page.
And yeah, Richard Feynman wasn't a youtuber, but he also isn't the be-all and end-all of physics either. He is worth listening to regardless of whether he is right or wrong.
However Veritasium is never worth listening to. Veritasium is a joke.
