"The fascinating thing is not that electricity travels down the wires. It is, rather, that were they not insulated it would not" Nikola Tesla

Fantastic revisit! The animations and the simulations were spot-on, and great at showing the difference between the transient “first-second” effect, and the steady-state “rest of time” behavior. The whole “expanding loop of current” thing is a great way to phrase it, because after that poynting loop expands to match the actual physical loop of wire, then stuff starts to behave normally and all of the power is transmitted around the loop very close to the wire. I still hold that for this simple circuit, turning on a lightbulb with wires much smaller around than they are long, the effect of surface charge vs internal charge is negligible, so you can ignore any skin-effect stuff and say that “mobile” electrons are indeed pushing on other “mobile” electrons using their fields, but I totally agree that that’s a simplification, just a simplification that makes the intuition a lot easier. I also need to do some math about how far the average “electron” is displaced in order to build the initial charge distribution around some typical circuit elements - axial flow is the only way I understand those charge distributions getting built, and this whole endeavor has made me think hard about what that means. Someday when I think I understand it better I’ll edit up my pt.2 response video - thanks for the shoutout! I’ve got a great experiment in the works to show the “expanding poynting loop” 😁

Yes there are fields both Voltage and Magnetic fields around wires. ..

BUT Both these are very small and almost insignificant below about 100 Voltage and less than 10 Amps. . . . But neither of these are responsible for the POWER down wires. . . 99.9% something % of the Power in Wires at DC and low frequency AC is due to the VOLTAGE difference between the wire ends, causing Current to flow down INSIDE the wire.. . .

Going into more depth really helps! It's interesting how everything is linked, em fields, current, emf, frequency, transmission lines, capacitive, inductive and mutual coupling, Fourier analysis...

What I love about this is that this is truly an application of the scientific method within the scientific community. One person (or group) makes an experiment and hypothesis, peers challenge/prove/disprove the original hypothesis, and experiment with their own experiments, explanations, and hypotheses, and then communicate back to the scientific community. This results in further testable hypotheses and finally consensus. Those that question science sometime feel that science is a collection of edicts set in stone foisted upon them by the elite, but science is beautiful because it demands challenge for it work!

Much better than the original video. The level of technical explanation is far more detailed. Feedback from the community was taken into account and an experiment was conducted to prove that the original answer was correct albeit with caveats which are also explained. One more thing that I wanted to see in the experiment is what happens when the cable is cut at both ends and compare the result for the closed circuit. With both cable ends cut the experiment should clearly demonstrate that the energy to the bulb is transferred via an electric field and not by electrons pushing each other through a wire.

You either accept Maxwell's Equations or you don't. If you do then the important issue here is that Veritsium's presentation relies on transients and the dE/dt and dB/dt terms. In the case of DC scenario, however, the current density J is the ONLY source of the B field so whilst factually correct Veritasium's presentation is misleading. Whilst the field is present the Poynting Vector E X B is in turn due to the movement of charge INSIDE the cable. Also as a veteran PCB designer I can confirm that none of the comments apply to DC-only PCB designs unless transients are important.

I can see that Maxwells equations are more complex and the Lumped Element is simpler to work with. A bit like calculating gravity with Newtons laws or General Relativity. I think I can understand how AC current works when I think about it in terms of alternating fields.

I think a better electrical analogy is not water flow but *Pressurized Air* The *Energy* of electricity (NOT the electrons themselves but the energy) are like gas molecules at an equal but high and constant pressure throughout the circuit trying to disperse in all directions. The wires are like very efficient but slightly porus pipes, while the electrical device like a light bulb is a *Release Valve* that makes use of that energy. The pipes ( *Wires* ) efficiently funnel most of the air pressure ( *Energy* ) towards a release valve ( *Light Bulb* ) Note: The Switch that closes the circuit in this analogy is not a valve, it just allows for a *Pressurized Environment* for the pipes ( *Wires* ) and the releasing valve ( *Light Bulb* ) The Battery in this analogy would of course be the Pressure Tank, but of 2 valves where it's air (energy) will only escape when both of it's valves are alowed to pass through the 2 pipes ( + & - wires ) out through the same circuit, releasing pressure out through a valve (light bulb) in the form of heat and light. This analogy explains things like Voltage and Resistance like why wires are less efficient the longer, thinner, and less insulated they are. -Porus pipes will release more air the longer they are (more pipe = more pores) while thinner porus pipes can't are unable to pass as much pressure ( *current/voltage* ) causing resistance. If there is no valve in the closed circuit the pressure ( *Energy* ) can only be released through the pores within the pipes ( *Wires* ) eventually bursting the pipes ( *frying the circuit* ) from the amount of high pressure. Would this be a better analogy for layman's terms?

That's great and all but I've lost respect for him, because he proposes a lightbulb that comes on instantly with any flow of electricity.

In other words, turning such a light bulb off would be much more impressive feat than turning it on instantly with an insanely long superconducting wire connecting it. The fact that he doesn't realize that his physical experiment isn't even remotely analogous to his hypothesis despite even having a lot of back and forth with someone who's made videos pointing out those errors has made me lose respect. Scientists are self correcting, Veritasium is not.

Thanks Derek, because of your explanation things are much clearer now like how even in the case of open circuit capacitor get its initial voltage as same as battery or the concept of AC supply and its effects. Also you've made me realise that I should have paid attention to my Electromagnatic Field Theory class I just got its score and it's 32/50 lol but all i did was remember some formulas basics and practiced many numericals from sadiku lol

This was a great video that actually helped me to understand electricity much better than I already had. And the way you handled all the other "reaction" videos was really top notch. Thanks again!

It honestly feels like a brand new genre of KZread Science. Idk how many other science videos are out there like this, but many of the best math and science KZreadrs were referenced in this epic meta-analysis of KZread science thought. This felt bigger, like vlog peer review. Think of the potential!!! Thanks Veritasium!

The difference in charge potential is what initially sets off the electrical field cascade. The field acts on the charges within the battery so they drive each other continuously, equal and opposite. Until the potential charge difference is equalized, and so then the circuit charges can equalize to a stable state as well.

I'm thoroughly enjoying your videos. Recently, I indulged in a couple of your content pieces concerning electricity and I must say, they're top-notch. I appreciate the effort you put into crafting these insightful resources. Now, moving on to a question I have: it's my understanding that energy transmission is facilitated by fields. Could you elucidate how partial energy loss, in terms of electrical energy, comes into play? My initial assumption was that the electrical kinetic energy, transported by electrons, was lost through collisions with atomic cores, thereby converting it into heat. Could you shed some light on this?

As an archaeologist and ethnobotanist, my focuses are about as far away from electrical engineering as you can get while still having a toe under the umbrella of “The Sciences”. I have an extremely curious mind though and I always want to know how things work and why they work. Before these two videos, electricity had been a MASSIVE gap in my knowledge of how the world around me works, and an extremely crucial one. Thank you so much for doing such an impressive job communicating extremely complex topics in a way that is both approachable for novices, AND intuitive in final comprehension. I have spent enough years teaching and around other teachers to be in awe of how effortless you make science communication seem.

Very enlightening! This part of physics at the microscopic level always causes a lot of headaches, but it's crucial for you to kill the problem. I still have some doubts, and you clarified exactly what I was looking for. Besides the initial pulse, a small current is established until the field, channeled by the wires, reaches the bulb and generates the maximum and permanent current. The wires are important, but even so, it's the field that transmits the energy, and this becomes evident when you discover how slow the drift velocity of electrons is. It's hard to say if your first video is right or wrong.

Yes there are fields both Voltage and Magnetic fields around wires. .. The voltage field radiates away from the wire, when there is voltage on the wire relative to the ground, and can not induce the current in the wire, and the magnetic field rotates around the wire when there is current flowing in the wire.. . . BUT Both these are very small and almost insignificant below about 100 Voltage and less than 10 Amps. . . . But neither of these are responsible for the POWER down wires. . . 99.9% something % of the Power in Wires at DC and low frequency AC is due to the VOLTAGE difference between the wire ends, causing Current to flow down INSIDE the wire.. . . I hope you now understand this, and understand how pulses will travel down the wire at about 60% of the speed of light, in the wire, and the EM fields are far too small to do anything across the 1 metre air space.

I'm glad you made this clarification, because I misunderstood the point. I thought the original video was suggesting that the full voltage/current would be present at 1m/c, which would make me question if this is a simulation and that's a programming error. This full explanation makes a lot more sense, and is actually something I already understood.

This video goes so deep that the boundaries between energy transmission by cable and by radio disappear. This is very complicated for a non-expert and can hardly be explained more simply than in this video. Thank you.

A transformer using the magnetic field of the primary wire coil to induce power to the secondary coil. I believe is what he is trying to illustrate by showing that with the wires close together, a voltage is jumping across instead of traveling down the lengths of the entire wire. It is inducing a voltage to the wire with its magnetic field.

@@famousadio was thinking the same thing but Faraday's Law (which is when you refer to coils and magnetic field explanation) is to create a new voltage source. The secondary end of the transformer is just another voltage source . In this video the unintuitive thing is the way in which a load can reach its energy from an electric source. . Can someone confirm if 11:22 is wrong or not. I've never heard of a moving electric field giving you an induced (induced because it is happening across an air gap) voltage. This video says 5V induced across the resistor and 14mW of power dissipated over the 'short gap' time before the bulk of the energy gets to it over the longer cable path. We know the cable has very good electric and magnetic permitivity properties which is why the energy doesn't dissipate away as easily. However across an air gap the permitvity basically sucks and is technically where all the energy is actually dissipated in an electric motor. The air gap in this circuit is just extremely big. Motor Air gaps are a key design and affect overall strength of magnetic circuit and motor efficiency. Only Faraday's Law is what I accept at giving you induced voltage to a new circuit across a gap but only from a moving magnetic field.

This cleared up a lot of questions I had. I would love to see you do a video on the "Lewin circuit paradox", as there are many related concepts here.

We don't learn it in Physics studies either, and yet it is described in Feynman chapter 27 of book 2 ("Field Energy and Field Momentum", you can read it online). While even Feynman calls it "nuts", he agrees Derek's understanding is what the equations say and is the correct understanding. The fact that simulations that solve the Maxwell's equations show exactly that's what's happening should be sufficient to convince us that it's correct, as noone doubts Maxwell's equations, which have never failed and are correct under relativistic assumptions (in fact the B field is a consequence of relativistic movement of the electrons).

Happy that you finally did the follow-up video. It's excellent and well thought out and adds some excellent new detail. It won't stop the nerds arguing though, the EEVblog forum thread on the video is up to 75 PAGES of debate, LOL. The argument comes down to the fact that most practical engineers do not need to think in these terms, especially at DC. But I think you can sleep well at night after this one. The only thing I didn't see mentioned was the Quantum Electrodynamics (QED) hypothesis that might ultimately trump Poynting and Maxwell when it comes to energy flow inside vs outside the wire. But I can understand how that might side track this video completely. I know the Poynting/Maxwell math still works out for DC, but it's just The Vibe. So it's inside the wire at DC for this crusty electronics engineer :-P Well done.

​@@EpicBunty Do we know everything? - Probably not. QED sound promising, and if true it likely trumps Maxwell/Poynting theory. In the same way that Einsteins general theory of relatively up-ended Newtons. What we already know - Maxwell/Poynting is correct, because it provides a method to explain things that verifies with actual measurements. But we also still use Newtons laws to do lots of practical stuff, there is just a higher level theory available. We can't be 100% sure that a higher level theory above Maxwell/Poynting does not exist. And even if there is, for almost everything we'd still use Maxwell/Poynting anyway. And as Derek explained, we still use Ohms law and lumped transmission line theory, and transformer theory, and antenna theory to do practical stuff, because we don't need to fuss over the details or exactly how the energy flows.

Thank you very much for this follow-up. So the first video was not really fair and needed a better answer. After all, that's how research work: find something, try to explain roughly, others come to help, and produce a complete explaination at the end. So, amazing job. I understood absolutely everthing!

Thank you for showing your widest audience the process that sets scientific understanding apart and above popular conversation.

I saw electrical pulse delays every day in the lab while working as an engineer at a major aerospace company. Since most signals were on PCBs, the time delays were in small nanosecond. While the electron flow is relatively slow, the field change is fast. Matching impedance (capacitance- inductance) of the cable or transmission line with the source and load best preserved the pulse shape. The rule of thumb is 1 nS/ft for delays. What appeared to be an initial voltage on the bulb may have been an instrumentation error related to how you attached the probes and their grounds at the source and load. And if you have a DC or low frequency AC current in too thin a wire, the heat generated isn't in the air or a ground plane, it is in the wire that is carrying the electron current.

Yes there are fields both Voltage and Magnetic fields around wires. .. The voltage field radiates away from the wire, when there is voltage on the wire relative to the ground, and can not induce the current in the wire, and the magnetic field rotates around the wire when there is current flowing in the wire.. . . BUT Both these are very small and almost insignificant below about 100 Voltage and less than 10 Amps. . . . But neither of these are responsible for the POWER down wires. . . 99.9% something % of the Power in Wires at DC and low frequency AC is due to the VOLTAGE difference between the wire ends, causing Current to flow down INSIDE the wire.. . . I hope you now understand this, and understand how pulses will travel down the wire at about 60% of the speed of light, in the wire, and the EM fields are far too small to do anything across the 1 metre air space.

People really need to remember that most engineering-centric views of the world are, at their core, useful simplifications. Just like how an electrical engineer doesn't need to think about quarks when discussing how semiconductors work (since it is more or less "irrelevant"), an electrical engineer also doesn't need to "fully" consider how energy is actually dissipated to a load, but instead must simply understand and be able to model (with a sufficient degree of accuracy) what is happening. As a computer engineer, I also like to think of this as an abstraction, similar to how someone writing software really doesn't need to understand "exactly" what the CPU is doing in order to sufficiently write a piece of software (unless you are obviously writing low-level code which interacts with assembly or something).

This is indeed true for transient or high frequency current. For low frequency and steady state however as a single LED (without power harnessing circuit) or light bulb on a battery needs for it not only to instantaneously to turn on but instead to stay on undisrupted, it certainly would need the long time to travel through an undisrupted cable and also sufficient time for the reflections to stabilise, i.e. the steady state to be reached.

In generator-tech trade school we learned the right hand rule, and that magnetic fields emanate and collapse from the center of the conductor outwards in AC flowing circuits. The magnetic field "cuts" its own wire as it expands outwards, and cuts it again when it collapses. This was how we were taught that AC accomplishes Faraday's rules of induction, that the expanding and contracting magnetic field cutting its own wire, and possibly coils of nearby wire, at a set frequency is the motion of the magnetic field cutting a conductor. This "self-inflicted induction" AC causes is known as inductive reactance. We were taught this is how transformers operate, with AC a must-have to bring "relative motion" into the mix which should induce current in all conductors cut by the ever-propagating magnetic field in and around the wires, and even in wires not physically connected to the circuit. We were never taught that this "breathing" magnetic field in and around the wires were accompanied by an electric field brought on by surface charge differential that was started and maintained by some power source. We were not taught that these two interconnected fields actually transfer the energy which causes the electrons to move. This inductive reactance can get so out-of-hand that it creates a counter-voltage working against the source of power. With more motors on the circuit, capacitors may be needed to reduce the counter-EMF. "Current lags behind voltage" when dealing with an inductive-heavy circuit load, such as motors. This separation of the voltage and current arriving out of sync is known as the power factor, expressed in a percentage. The inverse cosine of the power factor equals the angle of separation between the voltage and current. This video demonstrates that the "conductor hopping" nature of AC transformers that is mind-boggling to us is a more appropriate demonstration of how electricity works than the contemporary idea of electrons flowing through a closed loop circuit inside low resistance conductors. Fascinating. Thank you.
