Its amazing how well you give graphical tangibility to theoretical concepts. You often help me get a clear idea of a physic principle that often I'm fuzzy about, or even miss understanding. Thank you so much for your ability.
I wasn't getting the idea in this video, so I went back and looked at the capacitor and inductor videos again - as I was watching the inductor video the first part of this video started to make sense. : ) ... (very enjoyable videos)
@@EugeneKhutoryansky yes ur videos r very helpful to understand the concept, and it gives ans of almost all my why questions...very satisfying videos :) thank u
Wood actually would work as an inductor core better than air. Although the permeability of wood is only a tiny fraction of a percent more than air. It would make for an interesting experiment to try and measure the difference.
It's utter nonsense to understand something else when it's said that the inductor is wrapped around a magnetic material; you people must listen carefully rather than to imagine by looking at the colour of the core inside the inductor De VU2RZA
Love your animations, it's impossible to find animations like yours visualizing electronics and it can be really useful to properly understand electricity. Hope you keep it up, I really appreciate your videos!
Your videos are great for people with a strong mechanical aptitude like. The math makes so much sense one I've seen it shown to me from a mechanical approach!
I think a critical thing to note is that when the magnetic field first begins to collapse across the inductor, its voltage potential spikes to values much much higher than the voltage originally used to first charge the capacitor. Resonant circuits can achieve very high potentials while in operation, because of this phenomenon. Also, this explains more concisely why the circuit doesnt just find an equilibrium, rather than resonating. The sudden spike in inductor voltage causes a fierce inrush of current into the capacitor, only when the magnetic field begins to collapse, and not until then. Examples of this spike in voltage can sometimes be seen when a transformer is suddenly disconnected from power, resulting in a surprising high voltage arc from "back EMF". I hope this makes it easier to understand resonance. It used to frustrate me in college that most professors really didn't understand the fundamentals of what they were teaching. So, I sought to make this complex phenomenon as simple as possible to visualize.
@@arthurmead5341 yes. Pass a dc current through an inductor and interrupt the power supply with a switch. You should be able to see a sharp rise in voltage as the supply is removed.
re: "thing to note is that when the magnetic field first begins to collapse across the inductor, its voltage potential spikes to values much much higher " NO. This would NOT be linear behavior, and an L and C most definitely exhibit LINEAR behavior ...
@@uploadJ The following link is a demonstration of the phenomenon. A neon bulb needs much more than 9 volts to ignite. When a neon bulb is placed across an inductor whose 9 volt power supply is suddenly interrupted, the bulb will flash momentarily from the high voltage that appears across the inductor. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-T8O8aTO3ea8.html

Well, done. Any introductory electronics course should include this video as a practical visual understanding of resonance. Starting young engineers with the equations may be traditional, but a visual presentation such as this will provide a long-lasting practical understanding as well. Something I see lacking in engineers and technicians today. Keep up the good work.
Oh, I love these videos. Makes me think about these things in different terms, and also allows me to verify my understanding (because you can see how the laws are being applied as things are changed and moved around).
Your videos are just totally awesome! For me it cleared up A LOT. Through these representations it is so much easier to understand. Please, keep up the good work.
That was the best explanation I saw, nothing like the standard "capacitor loads the coil and vice versa" without explaining why does it behave this way.
I love the easy to understand animation as well as the strait forward,to the point narrative wich is also easy to follow.Thank you for your well produced production of your great knowledge that you share.

My professor was discussing this circuit and she was using the parallel configuration and she said at resonance the circuit blows up ,but when I went to compute the equivalent impedance of the circuit it seemed the circuit impedance went to infinity at the resonance frequency making it a open circuit and your video made that really clear.
En el trabajo no tengo más remedio que estar traduciendo y leyendo,cuando veo youtube es para desconectar . Saludos,hay millones de hispano hablantes en el planeta
I think inductors and capacitors are well represented by a hydraulic analogue. Inductors resemble a turbine which require energy to 'spin up', and in the absence of that energy, maintain their momentum until dissipated. Capacitors resemble a diaphragm, allowing a brief flow of current, but resisting it the harder it's pushed.
Good analogy ... Capacitors are like hydraulic pistons(or rams) (Electric Field ... Potential Energy)... Or Capacitors are like Springs (storing Elastic Potential Energy) Inductors are like hydraulic motors(or turbines) (Magnetic field ... Kinetic Energy) Or Inductors are like Fly Wheels(storing Rotational Kinetic Energy) Resistors are like Brakes/Dashpots Diodes are like Check valves Transistor as a switch is a Gate Valve/clutch Transistor as an amplifier/Transformer is a torque converter
Hey, I think it would be very good to add book references (or other source) in case someone wants to know more deeply about the topic in the video. Glad you are still making videos till now :)
These are the best explanations that i have ever seen before. At school before shwing matematical theories of circuits, teachers try to show understanding of how things works. So students may like what they learn so much, otherwise it is just a mess of memorizations of formulas that we see teaching. This is not an ideal way of teaching. Teaching doesnt mean to be writing the book on the board.
I have shown your videos to many of my engineering professors and they think these videos are incredible. The philosophy seems to be to make things as easy to understand as possible. Why would you ever want different? One of my professors wants to show some of these to their class! All of my friends are subscribing to your channel. Thank you so much for making these incredible videos, and from students and teachers alike, keep on making them!
+Peter Bayley, thanks for the compliment, and thanks for sharing my videos with your friends and professors. I am glad to hear that one of your professors wants to show my videos in his class, and I hope the students enjoy my videos.
+Peter Bayley, I would eventually like to make a video on phasor diagrams for AC electric circuits. I am not so sure about a video specifically on FPGAs, but I would like to make additional videos dealing with logic gates. Thanks.
Well said mam rest of all videos are mathematically but you explained practically in detail this is the actual process will going inside superb mam Make a video related how capacitor compensates reactive power in this manner
Thanks Eugene, another excellent video. It would be nice to see how high pass and low pass filters work (LC, RC, RL, RCL) with an AC signal. I get the idea though from this video.
