After 18 years of learning, i can say this is the most well rounded explanation I have ever encountered. Always leave it to the British to preserve knowledge for they preserve it with eloquence.
Professor: I was a "straight A" science student in high school and college. While I excelled in physics courses, I never knew what any of what I learned meant. Your presentation is so clear that for once, I finally connect the reality world and course contents - in circuit tuning and in ham radio technology. I needed to know this well. Your organization of material is outstanding and your articulation of the material was so clear and precise. It's such a pleasure to learn from you through this and other videos in your series. Truly grateful. Thank you.
This, in my opinion, is perhaps the very best video on youtube. I am a part time engineering lecturer but do not have an engineering degree; I do have quite a reasonable grasp of electronic and electrical theory though. I achieved an HND and between this and my industry experience I was fortunate to land my job (which I really enjoy). Some of the classes that I teach concern engineering principles such as the content you cover in this video. Having watched it I really have a far better understanding that I have ever had and more importantly I think I am in a far better position to deliver lectures on this subject. You truly deserve all of the glowing comments that others have posted ! Your channel is a must for subscription! Thanks.
@@jacobvandijk6525 That's a ridiculous thing to say. I was taught this stuff 40 years ago with EXACTLY the same examples and mathematics and my tutors learned it 40 years previously the very same way. Giancoli had nothing to do with that, this is the work of Coulomb and Ampere, Ohm, Henri and Hertz. We all have our favourite mentors but they all teach the same principles, with the same mathematics with pretty much the same examples. Nobody's copying anyone Jacob.
"Perhaps this is the very best video on youtube". Dear, o dear. You have a high opinion of yourself, don't ya? Next learn about Relativity! Then you know how subjective this opinion is. Nevertheless, you're free to think and say what you like! But a bit more modesty would suit ya, Andrew.
I was a Royal Navy Electronic Engineering Apprentice back in 1991. This is like doing that course again. A wonderful walk down memory lane. Thanks man!!
I'm 16 and have just finished my first year at Sixth Form. I have always had a strong interest in electronics and I plan to study EEE at university. In the past year, my interest has moved on more from making practical circuits to learning about the physics and mathematics behind electronics. I'd just like to say that this video is the first video I have found which actually explains LRC circuits in a way which I can understand. I particularly like the fact that you give mathematical proof for the resonant frequency equation towards the end of the video as one thing that has always bugged me when self teaching is the lack of proof for equations which causes me to feel that I don't fully understand the concept. Absolutely 5 star teaching, thank you!
Tons of thanks from Russia! I got it pretty smoothly though did struggle before. The explanation's utterly comprehensive. Indeed the great job, thanks again!
I bow to You - thank You so much ! I never experienced an explanation about that mysterious theme within 60min so clearly and logically.... i call it just great !!
Thank you for your time and effort in producing this excellent video. Doing Natural Sciences at undergrad' I know the time and thought that goes into *proper* explanations and derivations in physics of this standard. Excellent to have found an Englishman who also explains/derives in a more traditional sense, since this is more appropriate to British degrees. Thanks again!
This video is intended to look at reactance generally. So I didnt cover the use of caps in detail. One way of using a cap, as I briefly touched on, is to charge it and then to discharge it across a lamp. Caps can also be used to smooth out an AC voltage (as described in my AC video). You might like to look at some of the electronics videos on RUclips for more info. I haven't made such vids - at least not yet.
While I know this lacks a abundance of vocab to express how well this video made learning a complex issue is... DAAAAAAYMMMM. I've spent a long time reading documents trying to understand, you made it so easy to understand.
Two things about this video......I appreciate the simplicity of explaining complex concepts. (Complex by my standards anyway) Secondly, it just goes to show, that you dont need power point slide shows to make a presentation, and that that magic green texta of yours does a brilliant job. Full kudos to you !
Very good explanations, I like that you are explain how a radio can be tuned, I couldn't find explanations so clear in this directions!!! Many thanks !!!
I received a 'D' in my Alternating Current class and did not learn much. You are a far better instructor!! I am really understanding this a lot better now, thank you!!
THANK YOU VERY, VERY, VERY MUCH. YOU CERTAINLY HAVE A TALENT TO TEACH. I COULD NEVER UNDERSTAND THIS. NOW I UNDERSTAND IT. YOU MAKE SO SIMPLE. KEEP THE GOOD WORK. THANKS.
Thanks! This is the best explanation of these concepts I've ever seen. I think I'm going to be spending more time watching your videos in the near future...
Your videos are amazing. The concepts are clear and easy to understand for such a messy subject. They are the main reason I passed my college Physics B module, and for that I thank you good sir.
This is AWESOME. Very well explained. I'm currently learning electronics by myself (for fun), and this video helped me a lot. Thanks for sharing your knowledge!
Interesting guide! I am a Pole, not everything I understood. Know one thing, the math and physics is one all over the world! Thank you for your lecture
could've added one with parallel components but either way, hands down the best explanation I've seen :D thank you very much, sir! you've saved my butt for countless times now
Very good explanation and background information in determining the formulas associated with Impedance. Many text books and online material I have seen tend to use these formulas but do not explain in detail where they come from or how they are derived. Thanks for filling in the gaps.
You sir have done such a good deed by making these videos.... I mean you are awesome... You have made it so simple to understand all basics... Wowww... Salute to you... You hv inspired me...
As I've said, I really appreciate the effort put into these videos. They've helped me to wrap my head around some concepts I was struggling with. Have you thought of doing a video on passive/active filters? It would seem like a good follow-up video to this. I've definitely subscribed.
Thanks. When a capacitor is charged (ie surplus of negative charge on one plate and surplus of positive charge on the other) it stores energy and is in a state of high potential (rather like the storage of energy in a battery). If you then connect it to, say, a lamp, the capacitor discharges through the lamp (causing it briefly to flash). This is because the entire system wants to fall to a lower energy state.
Thank you very much for your videos, they are incredibly informative. I might be wrong but in this video you have only covered LCR circuits where their components are in series. Do you have any reactance and impedance videos where the components are in parallel? Or any resource (preferably a video resource) you would recommend?
This video is perfect! In my university a "professor" done the mistake you've showed in 52:44 !(and he said after it was not a mistake!) Thank you again

5 years later, you prevented a student from going insane. Thank you!

His presentation is good. But my true hero in explaining Physics will always be Mr D. C. Giancoli (in his brilliant books).

@@jacobvandijk6525 Dude, take a chill pill, ffs.
You've done more in an hour to help me understand several concepts than many hours of self-study have yielded. Thank you!
I've never ever seen such a clear and precise lecturer as you in my life. All I can say is WOW, and thank you.
watching this video seven years after your posting... this is perhaps the best explanation of these two terms !
I was a Royal Navy Electronic Engineering Apprentice back in 1991. This is like doing that course again. A wonderful walk down memory lane. Thanks man!!
This video has the best explanation of this topic, so so so clear...

the holy grail of impedance and reactance
You sir, you are my god! How come you can explain about impedance like that? Seriously. Deep love and best karma to you my friend! Thank U!
I have watched a lot of videos but this one was the most helpful. And thanks for examples, they helped a lot to put all information together!
I've just stumbled upon this channel. Thanks Bob for being such a good teacher.
Tons of thanks from Russia! I got it pretty smoothly though did struggle before. The explanation's utterly comprehensive. Indeed the great job, thanks again!

I just couldn't ask for more, brilliantly explained. Thank you so much!
Excellent! I studied this for my amateur radio exam many years ago and seeing it explained rather than reading it helps a great deal even now.
Just revising for my first year exams and you explain it so much better than my professor thank you
+Jonathan Davies Same with me. Where do you study?
+Nadezhda Dimitrova Hull,England
how about you?
Glasgow Uni :) UK universities,what can I say :D
Best video on the topic. Thank you!
this is hands down the best lecture Ive seen on Xc and Xl and exactly how and why inductors and capacitors function!
I 'm final year electrical engineering - this is the best for refreshing my resonance circuits . Thank you.
While I know this lacks a abundance of vocab to express how well this video made learning a complex issue is... DAAAAAAYMMMM. I've spent a long time reading documents trying to understand, you made it so easy to understand.
Great Lecture with brief but clear description.
It clarified my many doubts about reactance and impedance.
Thank you.
Thank you for this video. I've been self studying electronics with the intention of building amateur radios and this video helped immensely.
This is the video on this topic that gets my HIGH PRAISE! Liked and subbed!
This is actually one of the option subjects in the WJEC A-level course - this video has been extremely helpful, thank you.

Ben Frawley Magic is an understatement, that thing never ran out of ink or dried up!
I also give full kudos.
Very good explanations, I like that you are explain how a radio can be tuned, I couldn't find explanations so clear in this directions!!! Many thanks !!!
Crystal clear and precise - I'm considered thick but fully understood this!! Thank you for your time and effort in delivering an excellent video!
You are awesome i'm writing a paper on Impedance and this was the best explanation ever.
I received a 'D' in my Alternating Current class and did not learn much. You are a far better instructor!! I am really understanding this a lot better now, thank you!!
THANK YOU VERY, VERY, VERY MUCH. YOU CERTAINLY HAVE A TALENT TO TEACH. I COULD NEVER UNDERSTAND THIS. NOW I UNDERSTAND IT. YOU MAKE SO SIMPLE. KEEP THE GOOD WORK. THANKS.

Thanks from Sweden ....delightful and inspiring !
haven't found any other videos on Yt explaining so well this subject! thanks a lot!
Awesome explaination
This channel is a haven of physics for me. Live long sir.
Best explanation on the web, thank you very much!
One of the best explanations of the topic. Very clear and easy to follow with some basic background knowledge and math.
absolutley outstanding...learned more watching this video than I did in the classroom, thank you so very much !!!
Interesting guide! I am a Pole, not everything I understood. Know one thing, the math and physics is one all over the world!
Thank you for your lecture
just wow... great explanation and i can't tell how much helped me to understand this complicated topic. thank you so much.
10:55 I suppose, magnetic fields must be counter-clockwise at the top (dots) and 🔃clockwise at the bottom (❌) in the picture.
Absolutely well done. Very clear! Good teaching principles!
THANK YOU!! Finally found someone who CAN actually explain in a good way!
It really helped!
For real
I really appreciates all the videos developed by A Level Physics.. they are very clear and helpful...
thanks a lot
Great video. Very helpful to understand some hard concepts in a very good practical way. Thank you very much for the video.
omg you are just too good.. woow AMAZINNNGGG , you explain everything from A to Z.
Saved me on my EMD coursework thank you :)
could've added one with parallel components but either way, hands down the best explanation I've seen :D
thank you very much, sir! you've saved my butt for countless times now
there is no words enough to say thank you for your amazing video , I was lost with physic before i saw it
Very good explanation and background information in determining the formulas associated with Impedance. Many text books and online material I have seen tend to use these formulas but do not explain in detail where they come from or how they are derived.
Thanks for filling in the gaps.
Love you man, seriously. Excellent presentation.
Superbly explained why the higher frequency increases the Xl and lowers the XC
Great Tutorial love it like it you are a star.......
by far... BEST explanation of topic!
well explained !! I finally understand clearly the reactance thank you very much !!!
Thank you!!, this came just in time!
CONTINUE WHAT YOU DOING BECAUSE THIS IS YOUR CALLING... TO TEACH!!!. U MADE ME UNDERSTAND AC CIRCUITS.

I did not expect that accent, so I laughed a bit. Thanks for the explanation!!
Thank you so much, for giving a clear explanation in this video...
Great, clear like water . Thank you so much.
Brilliant video! It's clear, wery well explained and so much easier to understand :) Keep up with the good work!
Great Explanation! Thanks.
Thank you very much for doing this, i really appreciate your help.
Marine engineer student.
Great video, just what I was looking for! :-)
thank you for the videos, they very helpful!
this is amazingly helpful!! it's a shame that there aren't more like this
this is a beautiful explanation, thank you
well done beginning to actually understand and enjoy.
easiest explanation ever. i finally get it. thank youuu!!
Super excellent explanation... Many thanks
The world's best teacher thanks sir
Amazing video, help me A LOT. Thank you Sir.
Well spotted. Thanks. I've added an annotation. I got them the wrong way round.
Sooooooooo good. Thank you!

My teacher taught the class that electrons are neutral. I had to correct him
Thank you to take us to the basics
you are awesome mate keep it up
That was a great explanation of this
Thank you very much.
Very well done!
Excellent explanation, thank you very much.
See my video on "Fermi-Dirac and Bose-Einstein statistics - basic introduction"
I stopped reading my textbook to listen to your lecture
It was really helpful sir, it helped me a lot to explain the concepts to my son who is in
pre-university electronics course. Thank you very much.
great lesson ! Thank you Sir !
