Dope Tech Episode 2

<<@BeatriceBech says : I get that it is the electric field causing the electrons to transfer energy to the load, but why is it that in the simulations e.g. when you close the switch at 11 : 15 and you say current starts flowing, the electrons are moving ? Does this not go against the original explanation ?>> <<@EricPham-f8e says : Imagine if background all we need put the bulb where it supposed to be. Just like it you put human in the church they pray in the school they teach and learn in the field they grow and hard vest so the field is all determined and it knew birth and death before human know. That's why chinese study geography and usa build GIS>> <<@EricPham-f8e says : Light is every where all lightbulb does is reveal it>> <<@EricPham-f8e says : The law already written before the circuit is in drawing board just like a child fate is sealed before birth>> <<@mariogastelum1463 says : l saw a video about how electricity flows some time ago but l did not get it, your video makes it clear so now l get it.>> <<@JohnnyLu-x2d says : I have developed an original waste-to-energy theory called The Lumangyao Method. It utilizes Sugarcane Pressmud (also known globally as Filter Cake or Filter Mud) through a unique "Dual-Harvesting Hybrid Cell." The bottom layer operates as an Acidic Microbial Bio-Battery utilizing the mud's natural acidity to generate electricity. Simultaneously, the top layer features a Thermoelectric Generator that captures additional power from the mud’s intense biological heat contrasting with the cooler night air. This dual-harvesting system from a single agricultural waste has never been done before, and I am looking for international laboratory researchers and engineering collaborators to build the first prototype! THIS SYSTEM WAS CONCEPTUALIZED BY JOHNNY ARANG LUMANGYAO FROM THE PHILIPPINES>> <<@ILTYT says : If you cant explain something simply you dont understand it! In your first video you talk in circles instead of simply laying out the specific variables/setup, that result in your specific manicured "answer". Such as a pre energized circuit simply on a switch, or the fact that the light and power source are 1m apart. You make two half hour videos seemingly trying to convince people that the power in their homes does a straight b-line to them directly through the air completely bypassing the miles of wires.>> <<@Massiv3Butthole says : That’s not how it works!>> <<@Slats77 says : minutephysics is still my hero>> <<@lancancom says : I’m reminded of Platos allegory of The Cave! The idea that electrons push each other along the circuit is like the shadows on the wall. It’s an apparition.>> <<@juancasanova8434 says : The problem is that your first video makes no distinction at all between the initial voltage and the voltage once the circuit stabilises. These are not the same at all, and if the distance between the cables was just 50 meters, the initial voltage would be basically zero. Like yeah, it exists, but it's not the bulk of the power transfer that happens. That one takes 1 second to go through the circuit. The larger point that power is transmitted by the field is correct and important, but the way you made it felt (still does feel) extremely misleading.>> <<@williamcampbell9859 says : I guess it's just misleading terminology. You say "the light turns on" and people think of the circuit in a steady-state. What you actually mean is there is an interim state between switch and steady-state, and with the right configuration, it can be enough to notice before steady-state is reached. You are technically correct but in a vacuum it's sort of a moot point, not really worth all this effort to basically correct your grammar>> <<@Kolonyak17 says : Thanks for the video ı learned so much>> <<@maximilianmulller3743 says : I was researching a bit more and want to share some interesting add ons. Wave propagation speed in air is slightly less than in a vacuum (neglegible) The dielectric is important so insulators and their permittivity pay a role in slower field propagation, as they can go down to 0.6c. This of course doesn't play a role when the length of the air is high compared to insulators but may play a role when building this setup in a PCB for example The conductor material is important. Lossy materials with a finite, but not huge conductivity there is a field dissipation effect so that part of the field penetrates the material. This doesn't really define a slower propagation time, but the definition of "arrival time breaks" as the wavefront smears and you need to define a threshold for "action arrived". At 1m/c the effect is infinitely small and time is defined by what you measure as "effect". This also holds for copper as a non perfect conductor. If you think about very thin or very long wires, resistance increases attenuation and high frequency dampening. This doesn't mean that the "effect" travels longer, it means that there is no sharp edge/wavefront, or the effect is dampened. Starting to slowly destroy the definition of "on" and "off". I think this is quite interesting, as the propagation speed stays, but the definition of "time", "on", and "off" becomes more and more difficult to define. This doesn't mean, the time changes, but it means that the wire dimensions can have an effect on how arrival time is defined when looking into real (imperfect) materials. I find this quite fascinating, because this effect is always there even in it's slightest form when having thick copper wires that are not too long. But the thinner and longer the wire gets, the more the effect comes into play, while 1m/c still is correct but it loses it's definition. In this case I think it means: does the length have an effect? yes and no!>> <<@arnavkaranjekar9627 says : I prayed for times like these>> <<@Mitchjason1 says : What?>> <<@zaadbaad541 says : Electricity is magic>> <<@popeconstantine8839 says : Funny how this "revelation" blows minds in the western world, where ppl from Poland to china have been using naked wire for antennas and are goin "duh">> <<@SirPheobis says : Lol, your chain theory would also explain why the light would fire off as there are already electons on the wire and batteries hold potential not electrons.>> <<@SirPheobis says : ok, lets place 3 bulbs in the circuit each at a far end and one close, the closest should light up first. Science is proving, stop talking and do real experiments that prove your hypothesis.>> <<@harushmalcia7425 says : No. This is BS just trying to cover up/trying to make himself look better by saying he explained it wrong, it doesn’t work like that but because they have the money and know how to put words properly together a-lot of people will believe his BS>> <<@nevinrush2553 says : I applaud your courage to undertake this, and I think you are correct. The field does all the work.>> <<@yoshiosashida435 says : just wait till these people figure out transformers exist>> <<@jjcooler65 says : Whats a meter?? Never heard if that in the United States of America>> <<@sukhps says : i would like to imagine electrons this way: like the iron fillings align themselves to the magnetic fields, the electrons align themselves to the electric field!>> <<@josevictorino.9343 says : Cool video but can someone explain why turning on one switch doesn’t turn on all of the lightbulbs on the house?>> <<@王杰-f6k says : don't get scammed by Veritasium, and don't even bother arguing with him using those fancy electromagnetism formulas and laws. The guy just made a damn wireless charger. According to his own model, if you slide that bulb and the adjacent wires closer to the power switch, the light gets brighter; move them further away, and it dims. Why? Because it’s a fing* wireless charger! Moving it closer just bumps up the fing* transfer efficiency! In that bshit* experiment of his, if you just ground the two wires next to the power source and slap antennas on both sides of the light bulb, it would still work! Because it's a fing* wireless charger!>> <<@王杰-f6k says : Stop confusing people with all this unnecessary hype! Your model is literally just a gigantic wireless charger. During the first year, the electric field is propagating inside the wires; because this field is changing, it continuously radiates electromagnetic waves. The 1-meter section of wire connected to the bulb is essentially acting as an EM wave receiver. So for that first year, the bulb is powered entirely by low-efficiency near-field wireless coupling (wireless charger). Only after one year, when the signal finally travels back, does the system establish a stable, steady-state field and switch to high-efficiency wired power transmission. You just dressed a basic radio antenna problem (wireless charger) up as a 'circuit paradox' to chase views!>> <<@youtubeviewer4127 says : 6:24 wouldnt that be a magnetic field, because the electrons are moving? Or are both fields there, in the same place?>> <<@tusharbanne says : So if we have some electric field absorbing material around the wire, would the electrons not flow?>> <<@Jevin-gn1vv says : for me, electricity and magnets are all black magic>> <<@steveamerine7666 says : Still have no idea how electricity actually works.>> <<@easyinventors8653 says : I'm a jee aspirant. Your explanation is crystal clear for me but still I seek for explanation using formulas and conceptual analysis that u did. Thank u a lot.>> <<@THEONLYETP says : wow my post was deleted! Oh well! Very nice discussion. My opinion is the same on electricity and force fields. reality-does-not-exist-until-it-is-measured-confirmed-after-australian-physicists-re-conduct-the-quantum-experiment elementary-particles-do-not-exist-part-1/>> <<@zathaziel-m7n says : Whats stopping someone from disconnecting the lightyear long cable to transfer data quicker than the speed of light>> <<@large_MARGIN says : It’s really fun how people will make an entire response video based entirely on their own misconception.>> <<@sharongonzales2495 says : Wow! You are SO inspirational, how you handled this entire situation, the lessons you learned, and welcomed the input from others. What a great attitude you have. Thank you!>> <<@sixmax11 says : this is what good teachers do, they inspire thought in their students.>> <<@Miguel.Gallego says : You are great Derek, but as you make it clear in this video, you made a mistake in the first one saying that the main power didn’t go through the wire but instead through the air.>> <<@JordanResendizyo says : scientific rage bait>> <<@JordanResendizyo says : isnt it like pushing a stick thats really long and asking if it would push at the other side of the stick at the same time?>> <<@Firstlast-h6e4s says : As we actual electricians like to say we exist because electrical engineers need heroes too. 100% of electrical projects have engineering errors. But what do I know my family has only been building mass scale electrical projects for 101 years.>> <<@TTchjvcg says : Thank you for this video, very enlightening!>> <<@nagarjunaasam5714 says : Wait, wait wait. How did you come to the conclusion V=IR for your load in the short term ?>> <<@t00lape44 says : I did have a question,. If there's a break at the far end of the circuit, will the bulb turn OFF in 1 sec after it has turned ON by closing the switch? As you mentioned, the further the switch is from the battery the longer the bulb will take to turn ON. Well, should one consider the break as another switch 1 light second away?>> <<@김민정-j5n5j says : ❤>> <<@Jude-k3y says : So if the wire isn't closed, does it turn off in one or two seconds?>> <<@Piotr-n8s says : I called the original video silly and here you are: it was silly. Hats down for effort and honesty but this shows that there are limits of sicentific investigation of something you do not understand. There are many things wrong with the whole experiment, it would be too tedious to rectify them all in a short post. But at the most general level author confuses "some" electromegnetic disturbance (no matter how small) getting through (via all kind of "parasitic", secondary properties of a system) with serious transfer of power. The full transfer of power requires builing up magnetic field along the whole power line and that is a huge amount of energy BEFORE it can reach the load. The video explains how energy is stored in the electromagnetic wave but then it fails to recognize that this energy also comes from the battery. And it does not jump across 1m of air because the air is not a convenient environment for electric field to form (drastic simplification). So the electric field "has to go around" which requires building a huge amount of energy on the way. Matching impedance, "small" instantaneous energy transfer, etc are just various forms of confusing basic concepts of electrical engineering. What surprises me is that so many people with scientific background did not call this out. Perhaps if you just asked experienced electrical engineer you would be spared these errors. And not, you do not need Caltech lab to detect and quantify this phenomenon. I can do that with my my old scope I keep in my basement after retiring. I have seen it countless times. Actually a big part of my job was to engineer out the delay you are describing here. More luck with other topics.>> <<@Ol_Graybeard says : Tesla is smiling.>> <<@xkid4444 says : If there is no name for the initial jump in power, I'm gonna call it Derek's power... or Muller's power?>>
