But how exactly do the voltage and current propagate through transmission lines?

[@AJ.Ferguson]

8:42 is that the right minus sign? Or is it the one to the left of the gamma that represents a phase shift by 180°?

[@TheSiGuyEN]

yes! you are right thank you

[@alyasker2194]

you sir are amazing , a half semester of my professor trying to explain this and you swept every thing in 15 minutes. Brilliant!

I've been looking for a good explanation on impedance matching cause I never really got it in my fields course. This video has amazing visualizations and explanations. Thank you so much

[@alexfwfwfw4830]

One of the best videos I have seen about transmission lines. My congratulations!

[@systemmatrixa2702]

This channel is pure gold. Would love to hear more about power electronics or energy engineering from you :) ❤

3D visualization of these theories is so rare and you're doing a great job sir. Thank you for your videos.

[@aieousavren]

Wowwwww! Very excellent video!!! Beautiful animations, clear exposition, enlightening concept. Great job and thank you for your hard work! ❤

[@user-dt1zg5qh7r]

Great 4-D video showing the often ignored time and especially the imaginary part! Someone already pointed out the wrong highlighted negative sign by Gamma. The voltage/current amplitude triangular chart also is slightly wrong. Gamma is the same for both voltage and current (there should only be one circle for showing 1 + Gamma and 1 - Gamma), but the voltage/current amplitudes have different prefactors (by a factor of z_0) which scale the whole term in parentheses. If just showing 1 +/- Gamma, there is one circle and a clear way to see the standing wave ratio.

from an electronic engineer perspective this is absolute genious

Yes! This is AWESOME information! Ham radio operator and HUGE interest in radio here. This is the best explanation I have ever seen of this. I learned so much seeing this video! Thank you! Subbed and belled!

[@AK56fire]

Brilliant explanation and animations are great as always..

[@Wander4P]

I think there's a mistake at @8:45. That minus sign is the same for both current and voltage. I think it's the sign in front of Gamma which rotates the vector 180 degrees.

[@TheSiGuyEN]

Yes, You are right :)

[@alinezhadi]

Giving some practical examples using capacitors or ... would make this video more understandable for other students with different background who are interested in this topic.

I have to deal with real world transmission lines. However, my transmission line is much shorter than the wavelength of my generator signal (it is in the kHz range). I just cannot comprehend how standing waves will form in it. Do we need more complicated math for this case? Does your visual explanation still apply analogously?

[@TheSiGuyEN]

I think the answer is in the first video of my transmission lines playlist. notice that the standing wave pattern repeats each half wavelength of the signal. So if the wavelength is too large compared to the line, there's no standing wave and you can treat the line as a simple wire in circuit theory (super conductive wire with infinitely small dimensions). as a rule of thumb you can use the lumped element model if the line is less than (1/20)*wavelength. Hope that help

[@ndenjoyment6591]

Just a dumb question - why we took I is 180 deg shifted from V

[@luphiax4239]

why at 7:16 you say that the current is 180° out of phase if in the graph on the top left corner they are out of phase of 90°

[@lnz597]

amazing

Admin, do u have code for this video?

[@SravanKumar-jt1ot]

Where have you gone a decade ago 😫

[@WalterKiefer]

Wouldn't the power company use a capacitor/inductor to fix the signal coming back so that the impedance of the reflected signal is purely real?

[@dovhanimakhado2434]

There is virtual no way you to get rid of the characteristic impedance of a transmission line.

[@erikeriknorman]

Maybe

[@Poopoopeepee432hz]

Where’s the attenuation constant?

[@TheSiGuyEN]

so far in this playlist we assume lossless lines. I think it would be better to include losses in a separate video.

[@catfunt3404]

My professor is cool but god damn I cannot follow him or read his cursive handwritten slides

[@florincoter1988]

Voltage does not propagate. It is the measured potential difference between two points. Neither current propagates. It flows. Waves propagate.

[@bartolomiuschristoffel8108]

Bro do know u alternating current, electric field and capacitance on long transmission line? If u dont know check out him video about transmission line

[@bartolomiuschristoffel8108]

Did u think this direct current?
