Correction: We actually do create intentional transmission lines in circuits to have a specific impedance/filtering characteristic. It's mostly used in RF and high frequency.
A beautiful animation on signal transmission and reflection which is an often confusing key concept in transmission lines and systems. Thank you to all those who prepared this and made it available !

The switch causes the input voltage to the circuit to be a step function, which mathematically is the sum of an infinite number of AC waveforms. In general, whenever a switch opens or closes, this creates transients, where the inductance of the circuit plays an important role.
JP Carcamo, no you can not upload my videos to another channel. The only way to provide a translation is through the link above, which adds subtitles which people can choose to view when watching the video on my channel. And by the way, this particular video already has subtitles available in Spanish. Thanks.
This is the Best channel which successfully explains complicated rules, theories and pure basics of electric in an very clear and understandable way with very good animations. Very well done Eugene please go on producing vids!
The style of these videos is fantastic. The pace and vocalization are perfect. The only thing I would add as a critiques is that you can never restate/rephrase a concept too many times for the uninitiated.
The music goes from "Ah, yes, you see the voltage moves like a gentle wave across the wires, the voltage bobbing lazily up and down at its output," to "AAAAH F*** ELECTRICITY"
You have the best illustrations about engineering! Your videos are of excellent quality and high instructive value. Thank you for making the world a less strange place
I got to give props to the animator working with the music director on this project and also to the voice actor that changes to a much more sinister tone to extenuate the real-world implications this simple animation has
Always loved the art style of the videos and the narrator's voice. She enunciates like Microsoft Sam. The voice and animations work together to give the videos a surreal feeling that's pleasant and unique. Keep making these videos. I watch them all.
I work on J 1939 data links quite often. This explains the role of the terminating resistors. Now I better understand the transmission line at a more fudamental level. Thanks Eugene.
Have you considered making videos like this for substation concepts? As an Electrical Engineering student, I think it would be really beneficial for us to see the different substation configurations at work via the animations this channel offers. Just a thought. Thank you for all that you do!
What a great explanation!!! I've recently studied about the signal transmission and reflection in transmission lines to present a group work at the college. This video showed me in a more illustrative way how it works. Excellent!!!! It's good to have this type of content available on the internet. Great work!!!! It would be awsome if you post more content about transmission lines!!! I follow your channel and watch all videos that you post.
The video xas excellent as always, but it would be really interesting if you could make a second video explaining why this effects do happen instead of just showing them, in order to reach a better understanding of this phenomena.I know I may be asking too much for a TH-cam video, but I'm pretty sure you could make this happen. Great job! I love your videos!
Kritsu, this phenomena happens because the last inductor in the chain wants to keep the current going, so this current goes into the last capacitor, and as this last capacitor discharges, the signal is reflected.
+Physics Videos by Eugene Khutoryansky Wow great summary, fantastic video as always. I am disapointed in the human race for this channel not having more subscribers.
That's cool. Phone lines are a good example of a transmission line, you can actually measure the capacitance and we do it from the CO when someone reports a trouble. We can sort of get an idea of if there's even a phone plugged in based on the capacitance. Or if the line is even connected at CO. If the capacitance is 0 it means it might be open right at the frame locally. This got me thinking... wonder if DSL modems do some kind of impedance matching when first plugged in. That's probably what the "training" cycle is for. This reflection is also known as VSWR in RF terms. It will happen if the antenna is not proper for the frequency you're transmitting at. (I sound like I know what I'm talking about, but honestly most of this is over my head, just been doing lot of reading latetly. :P )
Great job, as always. You made my engineering career easy to understand with your videos. If you could make a video talking about Laplace and transfer functions would be awesome. Anyway, excellent video!!
Thanks. I am glad to hear that my videos have been helpful. I plan to eventually make videos on Laplace and transfer functions, though if you have not already seen it, you may be interested in my video on imaginary numbers, as I talk about functions of complex variables. It is at the following link. th-cam.com/video/bIY6ahHVgqA/w-d-xo.html
Great video, as always! It would be great if you made a video explaining AC power transmission (what happens in power transmission lines). I am an electrical engineer and I have studied transmission theory in Electromagnetics Course, abut I could never conceptualize or imagine what actually happens in transmission lines.
Excellent visualisation of something that confused me initially in my degree course, partly because reflections are not really part of everyday experience. Indeed, even now I hadn't appreciated that this happens with DC as well as AC!
Thank you! Your description is very useful. The dynamics seem to be the same as of a rope fixed at one end (without dampening).. is there a comparison of the equations available somewhere on the net? Keep up the good work!
Nice idea to animate it this way! Although it wasn't specifically mentioned in the narration, it also shows how the signal gets distorted by travelling through the transmission line. The sharp edged pulse becomes smoothed out.
Wow, I can't believe that so may people are worried about the music or the reference to Einstein. I work with transmission-line reflections all of the time and this is a great animation of exactly what is going on at a nano-second time-frame. Look carefully at each capacitor charging and the direction and magnitude of currents as the edge propagates through the conductor. My only suggestion would be to relate this animation (in real-time) to what you would see on an oscilloscope, because this is the information that you have when you are chasing down these problems. I wish I had something like this decades ago when I was trying to grasp these concepts in college. Thanks for the great animation.
At 1:10, I would have "inductance slows the current below the max speed through wire". Not that it is less than instantaneous which would violate special relativity. I don't see special relativity coming into this at all.
The bit about relativity is total nonsense. There is no prohibition against information travelling at speed C.. but in a practical transmission line, the L & C form time constants that limit the speed of transmission. This is the concept of velocity factor - which is the fraction of C at which the signal propagates. If you want to transmit information at C, then radio waves or other light (laser..) through the vacuum of space does that nicely. But via any physical medium, speed is always sub-C.
@@drlegendre Your comment says information can travel at c, which is true. The narrator said information can't travel *faster* than c, which is also true.
*The fact that the signal cannot travel faster than c has nothing to do with the capacitance or inductance of wires, it is just that the electric fields propagate at the speed of light (c)*
daam good video deff subscribing, it would be really nice to hear a personal voice though maybe the person credible for the idea of how to visualize it, the components raising a lowings in thier grid is a completely new but really really good way of showing the voltage thanks for ur time makin these videos i wish i woulda have found all these before i spent 15 grand on college lol

How about an antenna or three phases transmission line without neutral wire? Could you elaborate what happens in antenna? Thank you very much
Are these transmission-lines standing waves?

for dc inductance is zero ?

I have a dout can you explain?? please...
In Dc transmision there is no inductance effect so how we transmit the signal or electricity?
Wow! Wasn't even aware of this phenomenon. Thanks a lot.
Wow great content, love this type of ed video, very clear
Love watching the actual effect and behaviour of electrical circuit
This is great review and simple explaining ,, Thank you alot
