The first consistent explanation for a new experiment on #Veritasium's Big Misconception about Electricity

It was reported on 17 Dec by #AlphaPhoenix that the electric current through a resistor could be detected once the witch is on. It would appear this experimental result is consistent with #Veritasium's claim that it would take 1/300000000 sec for the electric energy to be transferred into his electric bulb from his DC battery.

However, this is not the case. As shown in this video, the instantaneous electric current can be explained in terms of Lorentz force acting on the electrons near or in the bulb whilst the magnetic field is simply associated with the moving electrons near the cathode of the battery.

Here is the link of the new experiment done by AlphaPhoenix:

The experiment actually down by Alpha Phoenix is great, but the explanations in his first video are incorrect. For example, he assumed EM wave was responsible for the propagation for inter-electron interaction. Like Vritasium, Alpha Phonexi believed that electrical energy can be transferred through the static electromagnetic fields outside the conductor wires.

Besides, the time scale in his experiment is too long: micro-second. Thus, it was impossible to observed the transient current in a few nano-seconds.

I won’t dispute your model. You’ve explained how the electrons start to move in the wire just after t=0. Instead I propose the ‘artifact’ current is in part due to the dissimilar types of materials. Wire vs tungsten bulb, wire vs resistor (carbon) and also wire vs. silicon junction in the case of a solid state transistor switch and LED. I believe I am correct as the movement of the electrons in the dissimilar areas will happen at a different rate. My instructors explained it like this: at the silicon junction there are actually ‘holes’ on one side where the electrons want to jump into. Also there are extra electrons piled up on the other side that want to jump out. It doesn’t take much to make them move. Note this isn’t reality- it’s a model that lets you think about what’s happening. So its not the battery pumping electrons that causes the artifact current- that’s too fast a change. But that they are predisposed to ‘jump’ to a dissimilar material as soon as any charge change is detected. So the experiment was already flawed by using a silicon junction as a switch, imho. The rest is explained by wave propagation at c.

Seemed all very well explained to me, until the point I was confused that you only considered the 1/6 of electrons that were thermally moving downwards. What would be the force/acceleration of the electrons that were moving in the other 5 directions, and what effect would they have on the net electron flow through the light bulb? Perhaps consider especially those that were moving upwards? (Sorry I don't remember my school physics so well.)

great!; in previous video (Poynting Joker), proffesor explain the requirements for applying Poynting vector theory

Dear Sir, I didn't see the link to the new experiment done by AlphaPhoenix.
