Transmission lines - a visual explanation

Eugene Khutoryansky provides another excellent (as usual) visual explanation for the mathematically challenged like me :)

The Dr. J.N. Shive's lecture also worth looking:

Thanks Kalvin,

It's refreshing to see a "vid" that is straight to the point without all the meandering that is characteristic of the youtube era. Good find. BTW, 1959 was an excellent year IMHO.

wow ... i hope i can show this to my high school and university professor , just to let them know how useless they are. i did read hundreds of documents about waves and reflection ... i can totally say this one goes directly to the point and it summarize it. well this was not a wasted 30 minutes of my life  :-DD

I think best for most people, is to translate everything to mechanics, because it is more visual.
This is called analogy between electronics and mechanics.
A capacitor behaves like a spring, the mass of a object is like an inductor and a damper works like a resistor.
https://en.wikibooks.org/wiki/Engineering_Acoustics/Electro-Mechanical_Analogies

But there are a million other resources to be found on the web.

The beauty of this is with control theory it doesn't matter if you're talking about train mechanics, an electrical circuit and even certain chemical processes.
It all has similar behavior with very similar formulas.

(and yes, professors have a tendency to make everything overly complicated, boring and even missing the whole point)
