In this informative video, we dive deep into the world of electrical circuits to uncover the secrets of resistance, reactance, and impedance. Join us as we unravel these essential concepts and how they impact current flow, voltage behavior, and overall circuit performance.
We start by exploring the relationship between voltage and current, emphasizing the differences between direct current (DC) and alternating current (AC). Learn how voltage changes influence current flow, and why AC circuits exhibit unique behaviors.
Discover how electronic components affect current behavior in both DC and AC circuits, with a focus on resistance, inductive reactance, and capacitive reactance. These components play crucial roles in shaping the current's response to voltage changes.
We use relatable water analogies to explain complex concepts, making it easier to grasp the fundamentals of electrical circuits. See how resistance resists the flow, and how inductive reactance and capacitive reactance introduce delays in current response to voltage changes.
Explore how impedance, the total effect of these factors, affects current within a circuit, providing a comprehensive understanding of these essential electrical principles.
Join us on this journey to demystify the world of resistance, reactance, and impedance, and gain valuable insights into the behavior of electrical circuits. Don't miss out-watch now to enhance your knowledge of circuitry!
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.
Glad to help
Yes- excellent explanation- much appreciated!
I totaly agree with you 👍🏻
Fix. Your name boomer

In my 4 years of studying elecrical engineering, never seen such a excellent example like this
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.
This is my kind of humor 💀

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!
45 years later, and I finally grok capacitors (in signal circuits, specifically). You did that. Thank you.
Thank you.

...and what have you done for mankind, dear friend ?
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.
You are welcome. Keep in touch.
This brought me back to my electronic engineering class! We were taught using the same analogy way back in 1980!
Ideal balance of brevity and completeness. Bravo.
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!!! 👍
Glad to help!
If a picture can speak a thousand words, a video speaks a trillion. And this video in particular proves that these statements are true. Thanks 👍
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.
Another way is to remember - CIVIL- Capacitor - I current leads Voltage, Inductor (L) , current lags Voltage.
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!
Loved the analogy with water flow. This video cleared alot of doubts i had. Thanks a lot👍
Very clear exposition, among so many contents useless to the dissemination of knowledge, here is something really well explained. Thank you very much
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!
The best explanation ever by using mechanical concepts. Great job!
So far it's the best visual explanation of concept I've seen.
absolute knowledge and I bet that my teacher woudnt teach me like that, hats off to U Prof Mad
Best AC Analogy to date my brother! This is going to help a lot of people understand impedances! 😲😲😲😲😲😲😲😲
Thank you.
why do you need an AC anlogy to date your brother?

Should also cover Admittance, Conductance, and Susceptance - Helpful in parallel circuit analysis.
please!
And reluctance, astonishments, and perplexems.
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.
Absolutely phenomenal with the explanations. Thank you Prof Mad for this
Excellent description of the topics with easy to understand explanations accompanied by clear diagrams.
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.
Best explanation I've seen so far. Thank you.
I have never seen as clear as this explanation.thank you bro.
This is the best analogy I've seen for inductance and capacitance.
Thank you.
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.
The best explanation I've ever seen. Thank you.
As a 1st year ham radio operator I wish my study materials had explained these terms as well as you did. Now it all makes sense.
Your lectures have the ability to make anyone understand engineering
nicely put together, well done! I only recently learned the differences, but this is an excellent: what-is-what explanation. thank you
Awesome, thank you!
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'm so glad!
wow....in a very simple way ..u cleared all d complications regarding... electric parameters
Hello professor, I just stumbled upon this video (while trying to find more information to trouble-shoot the compressor issue in my mini-fridge) and found your explanation awesome!. You are a good man!. Ashok
This was wonderful, thank you - best use of water analogies I've seen yet!
This video was a refresher for me. I am going to introduce it to my HVAC/R class. Thanks professorM
Thank you soo much.
This is perfect! I needed a refresher and you just summarized the last three chapters of my first semester so well. Saved me several hours :D
OMG this channel needs way many more subscribers
Unbelievable, this was simple and plain to understand. Thanks alot
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.
Thank you for your clear and precise explanation
VERY well done. Never understood this stuff until now. Excellent visuals and explanation. Thank you very much.
Glad it was helpful!
This video is by far the best video I have ever seen
Thanks for clearing the concepts.
this is the clearest video I've ever seen
thanks so much! Im a first year engineering student and this helped me a lot, God bless!!
undoubtedly it is the best video on electronics that I have seen

Best video found ever for this explanation.thank you so much❤
This is genuinely helpful for me in learning electronics, salute to you for giving us these great illustrations
Best analogy so far
Thank you very much Prof MAD, this helped me a lot.
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!
Wow, thank you!
Absolutely brilliant analogy.
Best explanation I've seen in my life.
Very clear explanations .
Absolutely top-notch material!! Simple, clear, memorable. Thank you! With content like this, Prof MAD will grow like MAD! Wait for it....
Much appreciated!
Great job, if only school and college would explain things this way. I'm gonna stick around.
Very well explained Prof. Thank you.
seriously, the best explanation of impedance. thank you so much
very good strategies and notable relation with the variables using the graphs. excellent.
Thank you, great and easy explanation !!!
Well put and illustrated. Well done.
One of the best video I've ever seen.
Best explanation about impedance that I ever saw! Thank you!
You're very welcome!
Tuvok narrating basic EE concepts is awesome 😉
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 .
thank you for the very clear and intelligent explanation that I just watched
Excellent explanation! Well done!
Your videos are defenitely valuable, thank you for your efforts
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.
Depends on whether voltage or current is constant.
Best channel ever in youtube, keep going please !
Really an excellent explanation for easy understanding. Salute.❤❤❤
Wow this is by far most the best I have seen so far. Sending to my kid 👦 right now!!
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
Very clear. Thank you!!!
Kids are so lucky with the amount of resources available to them. I am jelly, wish I had this stuff in my schooling.
best explanation ever, thank you so much
excellent video!! been a student of electrical for too long. This is great explanation.

I need to get this back in my head.
thank you very much for enlighting us
Awesome. Thank you. Very clear
Such an awesome explanation!👍
Great explanation. Subscribed. Thank you!
Very good animation and explanation. This video helps students to understand these concepts easily. Well done.
Very well explained using insightful animations/illustrations. 🦉
Thank you so much 😀
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.
Very well explained
The best explanation for the difference between resistane, reactance and impedance I have ever seen. Thanks for the video 😃
Simply beautiful. congrats.
This is absolutely great explanation.
Glad you liked it
I finally understand. Thank You.
Best explanation ever. More success
