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.
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!
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.
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'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 .
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!
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!!! 👍
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
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.
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.
In Navy electronics school, we learned about ELI the ICE man: voltage (E), in an inductive circuit (L), leads current (I) current (I), in a capacitive circuit (C), leads voltage (E)
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.
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
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.
Great explanations. I thought I had a question about the water wheel at 6:50 but after reviewing, seems sound. The way I remember which does what with regards to current lagging or leading in Capacitive or Inductive reactance is: If you have a circuit fed with a Resistor to a Capacitor to ground, the current in the Capacitor will initially be high as the voltage increases (It will initially be discharged and look like a short)....the current leads the voltage (Current being higher first) If you have a circuit fed with a resistor to an Inductor to ground, the current in the Inductor will be low as it initially resists current flow but the voltage will be high, later, the current increases so the current lags the voltage. (Current being Low first) Capacitance: Current Leads Inductance: Current Lags Hope this helps 😊 Hope I'm right...😏😂
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.
Thank you so much. That was fascinating 😀. I have an electronics lab in my apartment. I actually found a school that still teaches electronics. I'm going to start in December online. Right now I've been teaching myself from books I got from Amazon with experiments.😊
Dear Sir, I noted that you use conventional current flow. I, too, use conventional flow, but some of my professors would give us both a zero for in actuality current flows in the opposite direction. Notwithstanding, I spent 50 years in industrial electronics and conventional flow has never let me down, it is much easier to comprehend, even though it is wrong.😂 you must have been trained by Malveno. Me Too, I think that he is the best author to ever come on the scene.
I’m 60 years old and I have seen hundreds of videos on electronics. This is, undoubtedly, the best explanation I have ever seen. Subbed.

Capacitance: Current Leads
Inductance: Current Lags

Depends on whether voltage or current is constant.
