Outstanding graphical depictions and verbal explanations of these complicated electronics phenomena !! Wish I had these when I was studying engineering in college !! Thanks !!
I have been doing calculations for my class on these stuff, but I have never quite understood the mechanisms. THANK YOU FOR YOUR VIDEOS! Please keep them coming. You help more than you can imagine!
+Physics Videos by Eugene Khutoryansky its true. your channel has very awesome videos and it deserves a hell lot more subscribers than it does have right now! & what happened to twitter account? did u make it?
Marvelous! This is indeed very intuitive. I have understood current leads voltage in a circuit with capacitance and voltage leads current in a circuit with inductance, but I have not seen it like this. This channel truly is a goldmine!
Explaining the effect mathematically, the impedance of both Capacitors & inductances is proportional to the frequency electrical signal applied to them. (The impedance is simply the resistance of a components with its phase shift ᵠ ) For the capacitor: Zc = 1/(C*ω) For the capacitor: Zl = L*ω Where: ω = 2*Π*f (The angular frequency/speed of the signal) f: is the frequency of the signal C: is the physical capacity of a capacitor (in Farad) L: is the physical inductance of an inductor (in Henry) Zc, Zl: is the impedance of a capacitor & inductor respectively Knowing Ohm's law: V = Z * I, will let us understand those effects mathematically. But still the video made a great visual explanation for the effect.
who are you .? .. you made me cry .. things were never easy before watching this ...,each and evryone of them .. hats off you nothing can beat this , for sure
Your videos are amazing. They make learning physics intuitive, easy, and enjoyable. Only wish you were on youtube 10 years ago when I was learning this stuff in undergrad. Keep the videos coming and I will keep finding you subscribers.
As a visual learner I commend you on one of the best basic explanations of the subject I have come across so far. After much searching it was a relief to find this material. Well done. :)
Oh dear, the presentation was excellent. 5 years from posting the video, I can't see any comments appreciating her choice of music, that transition from Beethoven to Mozart when replacing capacitor with inductor was so sweet for my ears.
after watching a some of these videos in the channel., Im amazed at how well the animation illustrates whats going on.. it gives me a clear visual understanding of some concepts i had trouble learning in school. Thank you. Please make more physics videos and other subjects if you can. i greatly appreciate it
nice explanation. it is the only youtube channel i also ever seen providing very very realistic possible explanation with all kinds of combinations that exist in reality. thanks to Physics Videos by Eugene Khutoryansky
What is a resistor? How does current branch in a network of resistors? How does it "know" how much should flow in each branch? While some detail is given in science and engineering courses about conductors, insulators and semiconductors, resistance is described in several ways. Examples include i. The restriction to the flow of electrons. ii. The difficulty in moving electrical current through a conductor to which voltage is applied. iii. a circuit element which dissipates energy in the form of heat . More appropriate description for a resistor would be the property of a conductor which determines the current produced by a given difference of potential. This makes us remember that a resistor is a conductor first. And, there is reason to say that superconductive wires dont obey ohm's law. So all conductors are resistive, though not superconductors. Resistors are used in circuits to regulate the strengths of currents either by reducing the diameter of conductors or introducing more obstacles or lattice imperfections to reduce the strength of current. The current branches in a parallel network by an elaborate rearrangement of surface charge. For more details about resistance, how current branches in a parallel circuit and ohm's law consult the following videos, articles and books. Capacitive reactance The capacitive reactance is expressed in ohms and it is useful to determine steady-state current values to sinusoidal voltage inputs. Although the value of the reactance is expressed in ohms, it was not obtained by computing a resistance, as of resistors. The current in the wires of a capacitor circuit is due to the resultant electric field E(NET) (a resultant of the applied field and an opposing electric field, the fringe field of a capacitor), obtained by applying the relation for current density J = σE(NET), where σ is the conductivity of the wires. The field in the wire which may vary sinusoidally is always a resultant of the applied voltage which may be sinusoidally varying and the fringe field due to charge accumulation on the capacitor plates. For a comprehensive description of the mechanism of current leading the voltage across a capacitor see the book references below. Inductive reactance The inductive reactance is expressed in ohms, and is useful to determine steady-state current values to sinusoidal voltage inputs. It is to be noted that though the value of the reactance is expressed in ohms, it was not obtained by computing a resistance, as of resistors. The current is on account of the resultant of the applied field and an opposing coulomb electric field, which is due to polarization by the non-coulomb curly patterned electric field associated with the changing magnetic field, and the current obtained thereof by applying the relation J = σE(NET) where E(NET) is the resultant field of the applied field and the coulomb electric field and where σ is the conductivity of the wire.

Amazing videos! Always recommend them to everyone at work.... The knowledge gained will last forever through the ease of explanations shown through the animations and commentary! Don't stop! Thank you!!
+Physics Videos by Eugene Khutoryansky sorry for the typos...you're*, and capitalization. Also, what did you major in in school? Im guessing physics major. And what do you do now?
This is decent. When I saw this in the preview I thought "oh no... Not yet another crap animation that screws it all up"... This is not the case. Unique way of graphically illustrating what is going on. For a beginner this has to be one of the better explanations I've ever seen.
Even though I already wrote many exams about this, it was nice to have the simple RL/RC circuit and dependencies of impedance and current flow explained again. Nice job!
Great video! Also, you could make a video about the combination of capacitors, inductors and resistors in parallel and in series with Phasor diagrams and the coolest animations of yours!
Music is just too good, relaxing calming, with physics stuff going on, what else does one need The best!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
~ Alternating current conducts thru the outer material of a conductor, while direct current conducts thru the inner material of a conductor. The material's inherent properties determine the conduction characteristics.
If only I had been able to see this at High school. I am quite sure our teacher didn't understand what he was teaching, he certainly never explained it like this.
Very nice. A very good thing of your videos is that you are consistent with your graphical representations. That helps a lot. :) BTW, I was wondering if you could make a video on why gluons have eight colors instead of nine, or maybe six, and how should I call those colors? hehe... Gluons are weird...
Of course is crucial to be referred that this attitude of capacitor that is demonstrated in video,is applyed only if connection is "in line" onto a cicruit . In fact in line connection rerely is appeared in most circuits. A low amount of capacitance spontaneously is appeared between wires or between coils of a inductor ,both are connected parallel to their own electrical elements,and even a plus capacitor be added,for example onto a motor in order to correct the power factor ,then it will be added in parallel.Besides,the inductance follow the resistance of indactor which its own,so inductance can be connected either in line or parallel. So the impedance formula changes in parallel connection. Only in very special applies a capacitor is connected in line.
🇧🇷🙏🏼👍Beautiful work, you have a video showing how the Joules thief and its components work and how the electrons behave. Note: Joules thief with a 1.5 Volt battery can start a 12 Volt motor.
Amazing video, it helped me understand the topic of inductors and capacitors in circuits I really like the way your videos visualize things, it makes concepts easier
Nice, Eugene. Seems like you took the extra effort to make the music match other vids. The music changed to match the piece played in this vid on inductors,when you brought the inductors in to replace the capacitor. Well done sir
this is epic, any random shit content gets views these days, these videos are not properly appreciated, outstanding representation of all the concepts, blown away totally.....this is how its done...
i have literally watched all of the videos on this channel and i was waiting for the next one ;w; great visualisation of the concept and great description in simple terms!
Thanks. Glad my videos are helpful. Ideal capacitors and ideal inductors are unable to consume AC power, so the only component discussed in this video that would consume power are the resistors. I might make a video that discusses this in more detail. Thanks.

The correct formula for the energy of the electric current E=IU2/2 (of course, here you can talk about instantaneous power or add time) by analogy with mv2/2 because the voltage drop is nothing more than a drop in the initial velocity and it is quite obvious that there are no forces supporting the velocity in the conductor other than the initial conditions.
You will need to be careful with analogies, I think. For example, a capacitor stores energy and not charge. You will find my book useful, with a few analogies. But why analogies, if you understand the real mechanism? What is a resistor? How does current branch in a network of resistors? How does it "know" how much should flow in each branch?

Wait until you get into other devices, the fun hasn't started yet! 😀 I've often wondered how younger people would learn what many old timers know, with radio shack, olsons and others closed, and a downturn in publishing.
Perfect and Helpful! But there 's something unclear for me about " Inductor in AC", around minute 5:21 of the video: I think when the input AC voltage is at the maximum, di/dt will be zero, so the voltage difference of the inductor must be around zero (I said "around zero" because of the Resistor). And in continue, when the input AC voltage is zero, di/dt is at the maximum, so the voltage difference of the inductor must be around maximum. Please explain me if I 'm wrong. Thanks to your response in advance Eugene!
No, the equation for an inductor is V = L di / dt, where V is the voltage across the inductor (not the input voltage). So, when the voltage across an inductor is at its maximum, di/dt will be at its maximum.
@@EugeneKhutoryansky Thanks to your prompt replay! Exactly dear Eugene: "When the voltage across an inductor is at its maximum, di/dt will be at its maximum", but the question is: "when the voltage across an inductor is at its maximum?" I think the answer is: "when the voltage of the AC input is around zero!" Because the voltage of inductor is π/2 lead-phase than the input voltage. At the maximum of the AC voltage, the current of the circuit is at the maximum too, but di/dt goes to the minimum and zero, so the voltage of the inductor will be zero too. Am I wrong?!
Dear Eugene! I found out my mistake: The current of the circuit will be at the maximum, when the voltage of the resistor is at the maximum. And di/dt will be at the maximum, when the voltage of the resistor is zero! I should have replaced Vemf (the input AC voltage), with the voltage of the resistor! Thanks a lot for your perfect animations!

I have been doing calculations for my class on these stuff, but I have never quite understood the mechanisms. THANK YOU FOR YOUR VIDEOS! Please keep them coming. You help more than you can imagine!
Thanks. I am glad to hear that my videos are helpful.

Thanks for that really great compliment.
+Physics Videos by Eugene Khutoryansky its true. your channel has very awesome videos and it deserves a hell lot more subscribers than it does have right now! & what happened to twitter account? did u make it?
Thanks. No, I have not yet created a twitter account.
+Physics Videos by Eugene Khutoryansky ok👍
+Marc G true dat!
Voltage as gravitational potential is an excellent visualising tool. :)
And the red/blue tons of color in charging capacitor...
Pretty sure thats not what they're doing.. Its more likely that they're simply representing the amplitude of the AC voltage.. just saying.
It never be
both are scalar fields, so the analogy is fit
For a visual learner like myself this is gold. Thanks a lot! Amazing channel
Thanks. Glad my videos are helpful.
qualitative understanding not only necessary, but essential
many many thanks
Thank you so much for making this fascinating material accessible to those of us who would not otherwise even begin to understand it.
Glad to hear that my videos are helpful. Thanks for the compliment.
This is beautiful, finally I have an intuition for how inductors work, thanks.
Damn, even a presentation so well done like this can't make me understand physics and electronics. Maybe one day it will click in my head.
Marvelous! This is indeed very intuitive. I have understood current leads voltage in a circuit with capacitance and voltage leads current in a circuit with inductance, but I have not seen it like this. This channel truly is a goldmine!
Thanks for the compliment.
I absolutely love these electronics videos. They're amazing.
Thanks.
Physics Videos by Eugene Khutoryansky Keep up the great work. Best of luck!
Explaining the effect mathematically, the impedance of both Capacitors & inductances is proportional to the frequency electrical signal applied to them. (The impedance is simply the resistance of a components with its phase shift ᵠ )
For the capacitor:
Zc = 1/(C*ω)
For the capacitor:
Zl = L*ω
Where:
ω = 2*Π*f (The angular frequency/speed of the signal)
f: is the frequency of the signal
C: is the physical capacity of a capacitor (in Farad)
L: is the physical inductance of an inductor (in Henry)
Zc, Zl: is the impedance of a capacitor & inductor respectively
Knowing Ohm's law: V = Z * I, will let us understand those effects mathematically. But still the video made a great visual explanation for the effect.
There aren't words to describe this excellent work
Thansk for the compliment.

Thanks.
after watching a some of these videos in the channel., Im amazed at how well the animation illustrates whats going on.. it gives me a clear visual understanding of some concepts i had trouble learning in school. Thank you. Please make more physics videos and other subjects if you can. i greatly appreciate it
Thanks. I am glad you like my videos, and many more are on their way.
7:00 ah so thats why I can hook a transformer up to an ac outlet without causing a short!
omg hey! I love your videos!
Heyo, its Cody's lab. I was just thinking that these animations are a bit like the water voltage multiplier that you made.
Cody'sLab don't it heat up ? Like become really hot??
I always wondered that, myself.
transformer cant short because th primary and secondary wire doesnt connected
nice explanation. it is the only youtube channel i also ever seen providing very very realistic possible explanation with all kinds of combinations that exist in reality. thanks to Physics Videos by Eugene Khutoryansky
Thanks.
R u from ACE hyderabad institute?
Hello Eugene, fantastic visualizations to express the concepts. My compliments!
The most clear explanation i ve ever seen...hats off
Thanks.
I wish I'd watched it on the beginning of the semester!
I wish the same but 30 years ago
Efficient explanation, made me re think.

I was always cluttered with minutia.

What is a resistor? How does current branch in a network of resistors? How does it "know" how much should flow in each branch?
While some detail is given in science and engineering courses about conductors, insulators and semiconductors, resistance is described in several ways.
Examples include i. The restriction to the flow of electrons. ii. The difficulty in moving electrical current through a conductor to which voltage is applied.
iii. a circuit element which dissipates energy in the form of heat .
More appropriate description for a resistor would be the property of a conductor which determines the current produced by a given difference of potential.
This makes us remember that a resistor is a conductor first. And, there is reason to say that superconductive wires dont obey ohm's law. So all conductors are resistive, though not superconductors.
Resistors are used in circuits to regulate the strengths of currents either by reducing the diameter of conductors or introducing more obstacles or lattice imperfections to reduce the strength of current.
The current branches in a parallel network by an elaborate rearrangement of surface charge.
For more details about resistance, how current branches in a parallel circuit and ohm's law consult the following videos, articles and books.
Capacitive reactance
The capacitive reactance is expressed in ohms and it is useful to determine steady-state current values to sinusoidal voltage inputs. Although the value of the reactance is expressed in ohms, it was not obtained by computing a resistance, as of resistors.
The current in the wires of a capacitor circuit is due to the resultant electric field E(NET) (a resultant of the applied field and an opposing electric field, the fringe field of a capacitor), obtained by applying the relation for current density J = σE(NET), where σ is the conductivity of the wires.
The field in the wire which may vary sinusoidally is always a resultant of the applied voltage which may be sinusoidally varying and the fringe field due to charge accumulation on the capacitor plates.
For a comprehensive description of the mechanism of current leading the voltage across a capacitor see the book references below.
Inductive reactance
The inductive reactance is expressed in ohms, and is useful to determine steady-state current values to sinusoidal voltage inputs. It is to be noted that though the value of the reactance is expressed in ohms, it was not obtained by computing a resistance, as of resistors.
The current is on account of the resultant of the applied field and an opposing coulomb electric field, which is due to polarization by the non-coulomb curly patterned electric field associated with the changing magnetic field, and the current obtained thereof by applying the relation J = σE(NET) where E(NET) is the resultant field of the applied field and the coulomb electric field and where σ is the conductivity of the wire.
For a comprehensive description of the mechanism of current lagging the voltage across an inductor at different frequencies see the book references below.

Great explanation! After having read many books with surreal explanations, here you can find a short, realistic, clear one.
Thanks for the compliment about my explanation.
Amazing videos! Always recommend them to everyone at work....
The knowledge gained will last forever through the ease of explanations shown through the animations and commentary!
Don't stop! Thank you!!
Thanks. I am glad that you like my videos, and thanks for recommending my videos to your coworkers.
This is the best youtube channel which teaches us physics.
Thanks for the compliment.
Randomly i found this gem channel and my life changed.
I am glad that my videos have had an impact. Thanks.
Beautiful. the way you think about concepts is always very impressive. shows you truly understand what your talking about.
Thanks for the compliment.
+Physics Videos by Eugene Khutoryansky sorry for the typos...you're*, and capitalization. Also, what did you major in in school? Im guessing physics major. And what do you do now?
I love the creative idea behind the animation and verbal explanation of Eugene.
Thanks.
This is decent. When I saw this in the preview I thought "oh no... Not yet another crap animation that screws it all up"...
This is not the case. Unique way of graphically illustrating what is going on. For a beginner this has to be one of the better explanations I've ever seen.
damn it. it's late and my stubborn ass won't go to sleep until i understand this
Even though I already wrote many exams about this, it was nice to have the simple RL/RC circuit and dependencies of impedance and current flow explained again. Nice job!
I might add ,that the visualization is amazing. I rate 10/10
Thanks for the compliment.
Yet another good one. Thanks, Eugene.
Glad you liked it. Thanks.
All my students should watch your excellent animations to supplement the class materials. This fantastic.
Thanks.
Perfect to see why inductors act as low pass filter and conductors as high pass filters!
This is awesome... all concepts and worries clear
Great video!
Also, you could make a video about the combination of capacitors, inductors and resistors in parallel and in series with Phasor diagrams and the coolest animations of yours!
Thanks, and yes I would like to cover all those topics in the future.
I thought with the way this video was going it would talk about passive filters, but it pretty much set the foundation for it.
Best visual representation I've ever seen on this. Thank you so much.
Thanks for the compliment.
i love how you trying to make convince audience to understand with ur explanation at this video.. i love with your explanation consept in general..
literally, the best explanation of filters I've seen
Thanks for the compliment about my explanation.
Music is just too good, relaxing calming, with physics stuff going on, what else does one need
The best!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
~ Alternating current conducts thru the outer material of a conductor, while direct current conducts thru the inner material of a conductor.
The material's inherent properties determine the conduction characteristics.
I am studying for me FE and PE test and these videos are extremely helpful! Thank you so much!
Glad to hear that my videos are helpful. Thanks.
we expecting more elctronic circuit. I am so satisfied . Electronics is my dream. Thank you so much
I wish more people find this
Thanks.
One of my favourite TH-cam channel
Thanks.
One of the top notch educational video ever seen
Thanks for the compliment about my video.
If only I had been able to see this at High school. I am quite sure our teacher didn't understand what he was teaching, he certainly never explained it like this.
Your experience is normal. Most teachers who teach this don't actually understand it. Thanks.
Very nice. A very good thing of your videos is that you are consistent with your graphical representations. That helps a lot. :)
BTW, I was wondering if you could make a video on why gluons have eight colors instead of nine, or maybe six, and how should I call those colors? hehe... Gluons are weird...
First......
Person to say if you are watching this have a wonderful day
:)
Peter Feher thanks
Of course is crucial to be referred that this attitude of capacitor that is demonstrated in video,is applyed only if connection is "in line" onto a cicruit .
In fact in line connection rerely is appeared in most circuits.
A low amount of capacitance spontaneously is appeared between wires or between coils of a inductor ,both are connected parallel to their own electrical elements,and even a plus capacitor be added,for example onto a motor in order to correct the power factor ,then it will be added in parallel.Besides,the inductance follow the resistance of indactor which its own,so inductance can be connected either in line or parallel. So the impedance formula changes in parallel connection.
Only in very special applies a capacitor is connected in line.
This video is really good at explaining electricity.
Thanks.
Please do a video about quarks, and leptons and those elementary particles.
Nice way to show abstract topics. Thanks a lot!
🇧🇷🙏🏼👍Beautiful work, you have a video showing how the Joules thief and its components work and how the electrons behave. Note: Joules thief with a 1.5 Volt battery can start a 12 Volt motor.
Wonderful video! This cleared a lot of my doubts. Also I love the classical music. It only adds to the enjoyment while watching the video.
Thanks for the compliment. Glad you liked my video.
Can you make videos about aerodynamics?
Your videos are absolutely DIVINE. You make confusing topics comprehensible!!!!!!!! Thank you so much!
I already have a video on aerodynamics at th-cam.com/video/JSIPr9kcxdA/w-d-xo.html

Thank you. This helped me visualize how RC filters such as tone controls in an audio amplifier work.
Glad my video was helpful. Thanks.
Interesting way to present the changing of voltage and current
Thanks.
Very good! I'm studying electric engineering and this really helps me to get the visualizations in my head. Very good videos for picture thinkers!
Glad to hear that my video was helpful. Thanks.
your 3d works are wonderful, thanks a lot. keep making more videos.
Your videos are amazing
I have just started my engineering your channel is very helpful to me
Amazing video, it helped me understand the topic of inductors and capacitors in circuits
I really like the way your videos visualize things, it makes concepts easier
Thanks for the compliments. I am glad my videos are helpful.
Nice, Eugene. Seems like you took the extra effort to make the music match other vids. The music changed to match the piece played in this vid on inductors,when you brought the inductors in to replace the capacitor. Well done sir
this is epic, any random shit content gets views these days, these videos are not properly appreciated, outstanding representation of all the concepts, blown away totally.....this is how its done...
Thanks for the compliments.
merci de votre travail cela nous permet de comprendre mieux ce que nous avons appri au lycee
What a great explanation. Thank you very much.
i have literally watched all of the videos on this channel and i was waiting for the next one ;w; great visualisation of the concept and great description in simple terms!
I am glad to hear that you like my videos enough to have watched all of them. My next video will hopefully be ready very soon.
Amazing demonstration of circuit dynamics.
Thanks for the compliment.
very very nice efforts u alway help me in my confusions,during exams,to understand what everyone hasn't!! BIG THUMB'S UP!!
Glad my videos are helpful. Thanks.
The animation and narration reminds me of the old "Mechanical Universe" series
OMG! Never ever a teacher told like this. Thanks.
Glad you liked my video.
Avunu bro
@@EugeneKhutoryansky The world wants a physics teacher like you. We support you, Sir.
Sir, we want many physics concepts from you.
This video made me instantly understand basisc inductor functionality! nice
Best explanation so far.
Thanks for the compliment.
a beautiful animation thank you very much!! 👍😃
Background music can be disturbing though, the content is good, it's just the music that is not suitable
Hi. I find your videos really helpful and amazing. Could you please do a video on power consumed in ac circuits? Thank you for this amazing video.
Thanks. Glad my videos are helpful. Ideal capacitors and ideal inductors are unable to consume AC power, so the only component discussed in this video that would consume power are the resistors. I might make a video that discusses this in more detail. Thanks.
@@EugeneKhutoryansky thank you so much . I'll be waiting for more of your videos that will be coming in future
What is a resistor? How does current branch in a network of resistors? How does it "know" how much should flow in each branch?
While some detail is given in science and engineering courses about conductors, insulators and semiconductors, resistance is described in several ways.
Examples include i. The restriction to the flow of electrons. ii. The difficulty in moving electrical current through a conductor to which voltage is applied.
iii. a circuit element which dissipates energy in the form of heat .
More appropriate description for a resistor would be the property of a conductor which determines the current produced by a given difference of potential.
This makes us remember that a resistor is a conductor first. And, there is reason to say that superconductive wires dont obey ohm's law. So all conductors are resistive, though not superconductors.
Resistors are used in circuits to regulate the strengths of currents either by reducing the diameter of conductors or introducing more obstacles or lattice imperfections to reduce the strength of current.
The current branches in a parallel network by an elaborate rearrangement of surface charge.
For more details about resistance, how current branches in a parallel circuit and ohm's law consult the following videos, articles and books.
Capacitive reactance
The capacitive reactance is expressed in ohms and it is useful to determine steady-state current values to sinusoidal voltage inputs. Although the value of the reactance is expressed in ohms, it was not obtained by computing a resistance, as of resistors.
The current in the wires of a capacitor circuit is due to the resultant electric field E(NET) (a resultant of the applied field and an opposing electric field, the fringe field of a capacitor), obtained by applying the relation for current density J = σE(NET), where σ is the conductivity of the wires.
The field in the wire which may vary sinusoidally is always a resultant of the applied voltage which may be sinusoidally varying and the fringe field due to charge accumulation on the capacitor plates.

Thank you so much Eugene. These videos are helping me through electronics classes 👍
I am glad my videos are helpful. Thanks.
The correct formula for the energy of the electric current E=IU2/2 (of course, here you can talk about instantaneous power or add time) by analogy with mv2/2 because the voltage drop is nothing more than a drop in the initial velocity and it is quite obvious that there are no forces supporting the velocity in the conductor other than the initial conditions.
I enjoyed the explanation. Also include basic formula as physics always have symbols with it. You show the elevation in potential in appreciable.
awesome video. You are doing a great job.
Thanks.
Eugene is THE guy!!!!!
I think of a capacitor as a lake, a reservoir for temporary storage of electrons. I can't think of any mechanical analog for an inductor. Anybody?
You will need to be careful with analogies, I think. For example, a capacitor stores energy and not charge.
You will find my book useful, with a few analogies. But why analogies, if you understand the real mechanism?

Excellent viedeos!!
Thanks. I am glad you like my videos.
1:40 Well electronics got dramatic real fast there
Wait until you get into other devices, the fun hasn't started yet! 😀
I've often wondered how younger people would learn what many old timers know, with radio shack, olsons and others closed, and a downturn in publishing.
explained perfectly why current leads voltage in caps
Thanks. I am glad you liked my explanation.
Perfect and Helpful!
But there 's something unclear for me about " Inductor in AC", around minute 5:21 of the video:
I think when the input AC voltage is at the maximum, di/dt will be zero, so the voltage difference of the inductor must be around zero (I said "around zero" because of the Resistor). And in continue, when the input AC voltage is zero, di/dt is at the maximum, so the voltage difference of the inductor must be around maximum.
Please explain me if I 'm wrong.
Thanks to your response in advance Eugene!
No, the equation for an inductor is V = L di / dt, where V is the voltage across the inductor (not the input voltage). So, when the voltage across an inductor is at its maximum, di/dt will be at its maximum.
@@EugeneKhutoryansky
Thanks to your prompt replay!
Exactly dear Eugene:
"When the voltage across an inductor is at its maximum, di/dt will be at its maximum", but the question is: "when the voltage across an inductor is at its maximum?" I think the answer is: "when the voltage of the AC input is around zero!" Because the voltage of inductor is π/2 lead-phase than the input voltage. At the maximum of the AC voltage, the current of the circuit is at the maximum too, but di/dt goes to the minimum and zero, so the voltage of the inductor will be zero too.
Am I wrong?!
Dear Eugene!
I found out my mistake:
The current of the circuit will be at the maximum, when the voltage of the resistor is at the maximum. And di/dt will be at the maximum, when the voltage of the resistor is zero!
I should have replaced Vemf (the input AC voltage), with the voltage of the resistor!
Thanks a lot for your perfect animations!
