Im an ancient 493 year old man, and this is by far the great explanation i have ever seen across the centuries I have roamed this earth. Liked, subscribed, and rang the bell.
As Noah's 4,234 year old son, I have never seen an example as clear as this! Struggled understanding the concept before, now I can go and build the second tower of Babel without any difficulties. Subscribed!
I am 72 years old, hold a 2 year degree in electronics and was a product manager for 28 years for RF and DC calibration products sold directly to NIST. I wish your videos were around when I was a young student. Learning would have been much easier. Great presentation! Thanks!
Excellent. All stuff I knew 50+ years ago as an engineering student, but forgot. Great re-education for me.I cannot wait to see more of your videos. The diaphragm and water wheel did the trick to making it understandable.

Man- you made thing's so simple for me to understand! Given the much complex nature of stuff to grasp - your animations really are worthwhile n efforts r laudable!!! 👍
By far the best video on this topic, period. Brilliant explanation, brilliant analogy, brilliant animation. The world needs more people like you. Hats off to you and your team for working this hard!
I wish my old electrical lecturer (RIP Charlie) had access to this video in 1976. The best description of impedance I have ever seen. Thanks and keep up the good work.
I'm new to electronics, and some of the concepts are so hard to grasp. This is by far the best video I've seen, everything is SUPER easy to understand and extremely inspiring!
Nice explanation. Many moons ago when I was in the Navy electrician school they taught us "ELI the ICE man" to help us remember. Voltage leads current in an inductive circuit = ELI and current leads voltage in a capacitive = ICE. Of all the things I did forget that was one of the things which stuck.
Same with me. Except I was Air Force. One other thing I learned in my Air Force electronics training was that current flowed from negative to posiitive. After the AF I went to college to get an EE degree. There they taught current flow from positive to negative.
Thank you, thank you, thank you!! I needed this comparative visual so much. I was completely hung up on capacitive reactance until I watch the section on the elastic membrane. That's exactly what I needed to see to fit the pieces together in my head. Thank you so much
For someone that genuinely never understood electrical engineering as a whole -honestly not even 1% of it- ...Thought it was above my capabilities. Thank you, for sure a new sub!
I agree, was waiting to see how voltage/current lag would be shown with water, and the water wheel was perfect. There you can see without words how it works. Which has me thinking maybe the best explanations are ones that just boild everything down to untiuve bits, idealy without words, after all everything we're talking about is phsyical and we should be able to show what we're talking about with some sort of analogous action. I would love to see more mathematical relationships shown with action. I guess graphs are the closest thing but they're not intutive either, having to process mentally whats going on with a curve. Like a sine wave is circular motion through time but the graph doesnt make that obivouse. But say something like a gradient, you can see right away which parts are heavily concentrated which ones arent, its obviouse, a 2d graph you need to use a legend to figure out which was is up even.
The best way I remembered reactance from inductors and capacitance is ELI the ICE man. E for voltage, L for inductor, I for current, meaning voltage leads current in an inductance and I for current, C for capacitor, E for voltage, meaning Current leads voltage in a capacitor.
This video is certainly the best I have ever seen on this subject. I too devised this capacitor model of a membrane in a chamber many years ago and never seen anybody else using it before. I think that the only point you could improve is explaining that the paradoxical behavior of the current (or water) flowing ahead of the voltage (or pressure) being applied is due to the voltage stored inside the capacitor (or the elastic force of the stretched membrane). Of course that that does not work for the very first cycle.
Excellent excellent excellent just amazing and great way to make us understand I have seen several videos but no one made us understand like this thank you so much 🎉 Love from India
I'm fifth year electromechanical engineering student and this is the first time i see such a beautiful example to understand how impedance works. Thank you sir .
Resistance is the zeroth order reaction. Reactance is the first order derivative, in which an inductor opposes change in current with instantaneous change in voltage, and the capacitor resists change in voltage with instantaneous change in current. In brief, resistance is response to a constant. Reactance is a response change. Combining both reactive effects plus resistance, the sum is called impedance.
As engineer to truly understand some things we must concluded it or verses it all it types. Sir u concluded this topic so well. U must be are professor.
The elastic membrane analogy for a capacitor in an electrical circuit is genius. In most circuits it is hard to visualize that no current is actually flowing thru the cap, but there is still an energy exchange.
6:10 it is important to realize that the current in the circuit does not change. If water flows with (for example) 1 litre/minute through the narrow socket, then it also flows at 1 litre/minute in the wider tubes. It just moves faster through the narrow socket. Same in an electrical circuit; if you introduce a resistor, the flow of electrons (the "current") is the same everywhere in the (serial) circuit, including inside the resistor.
hello, what are you saying is that as long as the Force is the same in both cases, (case 1 pipe having same diameter, case 2 pipe narrows and then comes back at same diameter ) the flow of water would be the same? "Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy. The principle is named after Daniel Bernoulli, a swiss mathemetician, who published it in 1738 in his book Hydrodynamics."
I agree. Also, if the voltage is analogous to force, which in water flow is due to pressure, then the introduction of a resistor in a circuit should affect the voltage and not the current.
