This is exactly like I teach electricity, and electric current, that starts as waves of electron density inside the wire. And I guess that pretty much summarize the notorious question "does electricity flow in wires". Thank you for your video and your animations are beyond helpful.

Don't get too attached to the model shown here of electrons as little ball bearings lined up like ducks in a row, patiently waiting for someone to close the switch so they can start moving. The conductor in a wire is a crystal lattice of gazillions of metallic nuclei whose electrons (29 for each copper atom), exist in the surrounding space. The electrons are in constant random motion whether or not a battery is a part of the picture. When a battery is connected this motion becomes a little less random and tends toward the source of positive electric charge at a drift velocity which is far less than the speed of light. What is felt almost immediately when you close the switch is the electric field.

Sir, You need a different potential (negative and positive) setup in water channel to match electricity and they match the potential stay for some time to make current/flow.

Me finding a girlfriend is a low entropy state

Kind of like the ship of Theseus, if you replace one board at a time, the system (ship) will remain stable and appear unchanged, whereas if you replace every plank at once, then you have a completely new system.. not sure what I’m trying to say here 😅

This is the way youtube was meant to be used

wouldn't discharging a capacitor across the wires be better than using a battery in this experiment?

This is the most impressive video and explanation about electricity I ever saw.

I have no words just thanks a lot 🙏

You induced a currant and created 3 separate electric fields. Cool. You went into the first field, ran the currant out and slit it into two field one shorted and one not. Correct so far? Why would I be surprised to find out that the shorted field would take longer to saturate than an open one. Even though the open field has no where to go, that does not mean it does not have a voltage potential. The reason we use twisted pairs is to combat induction crossover in high speed circuits.

There is an easy way to introduce concept of entropy, without introducing entropy. Assuming a set of moves with some probability, and always fallow them according to this probability; You end up with a phenomena very similar to entropy itself. For example, if you have an open container, it is mor probable to move to the empty space, than to a crowded area. The same it is more probable for ink to go from a drop to the solution, than from the solution to the drop. The same applies with basically anything, until the probability is biased toward some point (e.g. a point of attraction).

You just gave me an 'aha!' moment when you're separating the ink from the water. That's exactly what is also being done in a desalination plant, as seen in Practical Engineering's video.

Less entropy isn't equivalent to more energy but to more *available* energy

C

this explained it so well, i like it

Amazing work! It's kind of mindblowing how far we (well, the giants whose shoulders we're standing on) got *without* the experimental capability to observe at these timescales.

Guessing what will happen before watching the rest: The initial state of the wire is uncharged. For simplicity let's assume the negative terminal is connected first and settles. When connecting the positive terminal, a "wave" will propagate through the cable and split at the junction. The field will propagate to the end of the unterminated end and a small amount of current will pass between these wires as the mutual capacitance of the twisted wire pair is charged. However once the capacitance is charged, no more current will flow. Technically the wave will reflect on the unterminated end, but let's not bring that into this. On the terminated branches the same wave propagates all the way to the negative terminal and as the EM field is established and there's an electrical connection, the current will flow.

Veritasium level explaining + >steve mould level demonstrating. Very well done, immediately saved to my physics playlist!

NICE CAPTURE how you diffrentiate when to capture more light in certain areas to see the stars

Ohmmmmm... Ohmmmmmmmm

seeing the distance apart of your wires i will say your getting induction on the table

Thank you so much for this demonstration. It is absolutely amazing to see. Brilliant!

Nope

That was excellent. TY The behavior you're demonstrating here seems like it could also be visually represented using hoses and pressurized water.

D. Is my guess

do a strong magnet or a transreceiver using the cropper and share a video. i am struggling to understand how the drones antenna works i mean they transreceive for long distances but they aren't huge transrecivers.

So if im not mistaken, the fastest a spring could decompress is at the speed of sound

Thank you!

Jup. A for effort

Wow, great visualization!

16:18 bro is racist

Don't forget the electromagnetic field around all conductors, that is transmitting the push-impuls, of the valence-electrons that jump out of the orbitals of the conductor atoms! it is like coupled freight wagons, where the coupling-impuls goes through almost immediately (voltage), but the "work" of the current only starts when the freight wagons have the tensions (are straightened) and start pulling, doing their "work", that is start causing a "resistance" in the metal grid !

It looks like you're using a battery to power this experiment? The battery is built out of a series of cells stacked together to produce its voltage. The current that flows through the circuit is generated by chemical reactions inside the battery. While there is a static voltage potential across the battery terminals before the electronic switch closes, no current is yet flowing through the wire. When the switch closes, the voltage potential causes current to flow out of the battery, which triggers chemical reactions inside the battery that generate additional electric current. However, those chemical reactions take time to accumulate within the battery, which may account for the one microsecond delay where a small initial current is observed before the main pulse occurs on the oscilloscope trace. ua-cam.com/video/PXNKkcB0pI4/v-deo.html

maybe I need to start calling my scope a half billion frame per second electronic camera 😂

Even though I already understand ohms law and work with control systems and electric motors i still enjoyed the visual explanations of ohms law. Specially voltage. My 24v control switches control 480v motors.

You could put a metal wire going in the line that divides in half the wood frame, then use slightly bigger black balls that can't fit under it and would rebound. Maybe something worth trying to see what happens statistically!

One addition to the video might be informative: after getting the steady state at the end, overlay a skeleton of the steady state outcome to the colorized flows earlier. This would show areas that are over/under their eventual steady state. But otherwise a great video. I have never seen someone attempt something like this.

Couldn’t you have used a logic analyzer???

Показать четыре атома? Что куришь мальчик? Хватит обманывать людей

What voltage?? What’s the voltage drop?? Then the speed of the circuit…. This is a good experiment. Thanks.

I'm very grateful for this video and explanation. The animations were so clear, I could finally understand what voltage is. Thank you🙏

I'm afraid I don't only believe it's possible for you to win the lottery every day for the rest of your life. Even for a theoretical immortal being, there has to exist a possiblity that he will win the lottery every day forever, otherwise probability feels wrong.

Amazing video! People like yourself making high quality videos of difficulot subjects is what makes UA-cam invaluable.

No, it doesnt. Save your time watching this Its 5th grade physics class (at least where I m from). The resistor in the medium decreases it to up to 30% of c. Thats it. Now go on with your life.

Try the resin in the vaccuum chamber before appliction maybe?

ok wait this is the best video i've ever seen.... about math or science.... what you've accomplished here is extraordinary

TENET ruined christopher nolan for me and now also chemistry/physics. thanks

Same principle as to why there are wars. The energy required to make billions of people agree with the same stuff is out of this world. Thermodynamics are awesome.

This is a very good explanation, excellent work.
