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.

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.

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.

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."
@dexterlyndonsabusap1192
@dexterlyndonsabusap1192 11 ай бұрын

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.
