This channel is very underrated. For the effort you put in, You should have a million followers by now. Thank you for the wonderful content.

Genius! Thanks saVRee! Everytime I watch your videos I realize that my university studies was piece od crap.
You do great things.

Great work
..This explanation is better than those professor in my college ..

[marcin]

I tried to understand that couple times. And I failed each time even I was reading amd watching that stuff in my native language. Here for me in foreign language that video explain it very nice. Big thumbs up 👍

[petrichor]

Those things I wanted to know, concise. Bravo

2:19 "some people waste their potential... In engineering, it's the same. " 🤣

Dumm gut gemacht. Hat mir sehr weitergeholfen

Why yours some videos in playlist is not available like videos in diesel engine playlist is not available

4:04 4:49 Is not that accurate. The post is right, it is like pressure. But the explain is wrong, not the number in electron difference cause them to flow.
The difference in electron numbers is not relate to voltage, even the both side got the same number, it will still flow under correct circumstance.
The accurate explain might be the tendency of water flow from high energy to low energy, as the tendency of electrons flow from higher energy side to lower one.
The voltage is create by difference in electronegativity, which is just like the hight of waterbody.
Just like water, you can create a lot of pressure with minimun amount of water, you can also create very large voltege with minimun amount of electron.
The number of electron is about how many energetic electrons are ther and thus count the total capacity, same as we count the volume of water stored to find out how many energy are stored in the system.

Also minor mistake in 4:23 is that both in turbine example and the circuit, now pressure difference is not equivilent to no flow or nothing is moving, in microscopic scale particles is always moving as the temperature is not 0K, each particle have its own chance move toward specific direction, but in macro scale they have statistically sums up to 0 velocity towards any dirction. Theer's still chance that at some point they all got the same direction and become flow, but the chance is an astronomical number in macro scale and even if that happend, the pressure difference created will immidately force them back to former state.

Nice explain still, there's so many things in engineering that fascinates me as I dive deeper into it.
