There is something wrong with your measurements.
At time 1:44 the current waveform should be showing a time constant and "rounding" of the leading edge as well as the trailing edge as shown to be occuring. The waveform should be symmetric.
This is really strange. It seems you are using an oscilloscope to read the voltage across the resistor to get the current but your waveform is not right. How did you do this?

If I could love this video, I would a dozen times. It's incredible how taking the time to make a video with examples is a thousand times more helpful than a textbook for everyone who prefers to learn visually or hands on. I've never been very good at learning much from a book.
we are a manufactuer for inductors components, i wonder if you have interesting? thanks.
Finally. Very ,simple ,and obvious explanation. For more than ten years inductors were magic to me. I never needed to use them in digital circuits but always was wondering how they work. That is so simple! Thanks. Do more videos about them! Also about units used and transformers.
Using a square wave to demonstrate the effect of frequency on the behavior of an inductor was used to great effect in this video. Just looking at time/current plots doesn't often get the point across but showing how a series inductor can transform a square wave into a triangular waveform (and explaining the current lag) really gets the point across. Thanks.
that was incredibly comprehensive for a four minute video.
It helped that he stated exactly what inductors do right at the beginning. Store electrical energy in the form of magnetic fields.
Yess
Great job, it’s hard to find videos today that can do things simple enough for you to understand but still gives a basic understanding of things.
I learned more from this video than years in school.
where the fuck did you go to school
Same. $30,000 / year university vs 3:53 minute youtube video.
YumYumOrYuck, sounds like Trump university you went to.
Sounds like you were in an arts course.
Only if you would have paid attention in school..
Your videos are short and too the point. THANK YOU! Very educational
the best video explaining inductors I've ever seen... thanks a lot.
You have kept me interested enough to warrant a subscription. I am learning electronics on my own and need explanations of what is going on in circuitry. You make learning fun! Thanks for posting and I will be viewing more of your videos.
oh boy this is the best ever video based on inductor, you have so much clarity in the concepts
Great video mate. Really appreciate how succinctly you summarised the topic.
I love your use of an inductor to show the action of an inductor. That is the kind of thing that gets people thinking.
Thanks for this video! I'm studying for finals on Electricity and Magnetism and this video really helped me to understand inductors. You made it way easier to understand than my Physics professor. Thank you!
this guy is a great teacher
Thanks bud!
I know this is a two years old comment. I have nothing against this channel except for thanking them. But to be honest with you. Its not about how great of a teacher he was. Its all about how much attention you're paying to what he said. Watching a video seems to be the best method to attract your attention thus allowing you to absorbed the information without any disruption or disturbance(if that even a word). I've observed that many people would instantly understand a topic if they were to search an explanation over at youtube or internet. This perhaps because of your willingness to pay attention. At school, You are most likely forcing yourself to understand which has backfire on your memory instead of absorbing information you have block your memory for you have no interest in learning.
@@mandingo4698 primarily because of replay button imo
@@narutouzumakix9201 YEA! And I can go back 5 seconds when I needed to :D
This is great! I studied modules on fundamental electronics in the earlier years of my course but it's all a bit fuzzy now so this saved me a lot of time. Nice one.
There are people out there who tend to complicate even simplest things. You, however, have the gift of making complex ideas simple and easy to grasp. Thank you.
My favourite electronics channel! Keep up the good work.
Outstanding video and explanation. Thanks!
this was an excellent video. i came here because i'm in a networking class and learning that fiber optics is used to eliminate the problem of inductance. you explained everything perfectly. thank you
I'm really enjoying your videos, your method of teaching is excellent, thank you!
Wow, what a clear explanation !
I wish I had seen this video a long time ago, Lol.
Thank you so much for the clarity - this is well presented .Thumbs Up and subscribed !
Cheers, gk.
Great video, thanks for taking the time to make it, you're an excellent teacher.
you had me at "Generally Speaking..." the best of the best that I have seen. thank you.
Good video! Covered basics and showed some unusual aspects as well.
Great videos, best i could find so far about inductors
Perfect video. Thank you so much. You educated someone today.
You are surely raree and unique. Hard to find someone with this knowledge and is great teaching and sharing it to ppl.
i am so glad i found ur videos, they r AWSOME!
Thankyou! Very helpful! And you cleared up my questions with capacitors!!
extremely helpful video!! i hate physics and this is my last semester, but i'll start watching your vids, really helped, thanks a lot.
Wow! Now I understand it.
Always wanted to know how inductors work.
Many Thanks for imparting your knowledge.
Excellent video !
Thanks for taking the time to make it !
I love your videos! Keep up the great work!
I love electronics but my learning disability prevents me from keeping up at school. Your video is very helpful to me though, because I can learn at my own phase by watching your videos anytime I want.
Same issue here. I'm glad these people take their time to help those in need.
serious: can you explain or describe your learning disability? I am genuinely curious about how something like that can come about, and how specifically having such a disability hinders your ability to learn? thanks.
megamanxu I'm at the bottom of the class no matter how hard I study. I sometimes bang my head on the wall during exam week. Some of my classmates at high school have a bad hobby of cutting classes and sometimes drunk but they still got better grades than I do and I never cut classes. I live in a developing country and although I never been evaluated by a doctor and diagnosed with learning disability but I know that I must have some learning disability by comparing myself to my classmates.
bobskie321 Electronics classes in many schools are mainly taught with giving the students the theory of how things work and then they can apply that learned theory to experiemental labs. It has been done that way for decades. For a lot of people, they eventually learn the abstract concepts by rote memorization while filling in gaps of practical knowledge with labs and later throughout their career.
For others, leaning these multiple abstract concepts is just too much. There is nothing concrete for their minds to figure out and they go into a hopeless tailspin of despair thinking they are somehow broken because the other students get it.
Nothing can be further from the truth. First, you just learn differently. Nothing bad about that. Second, most students don't even grasp the significance of what they are learning until 2 or 3 years later down the road, but they are fortunate enough to be able to memorize so they can get through the tests.
You can learn this stuff, and you are by your own admission. Quit selling yourself short and seek out more remote learning outlets (like these videos) for your learning. I'd also suggest a few self learning books on electronics as well. Eventually, your brain will have enough practical knowledge that the theory will start making sense. And even if it doesn't, there are plenty of people in the work force that know how to apply real world practical skills without knowing the background theory. Just know where you can apply those skills and where you can't.
Best of Luck to you - and keep on trying!! :)
bobskie321 just start learning from d basic..every line u read of d book just keep asking your self why m doing this untill n unless u get d satisfactory answer ...nd when u got it..go to d next line n do d same thing...
nd u will rock..good luck dont give a damn to grades,, ur knowledge nd understanding is much more imp. good luck with that :)
Explained in very easy terms. very helpful. 👍
you sir are a legend the way you describe things!
Damn! If I had seen this video 20 years ago ... I guess I'll have to build my own fluxcapacitator and find a power source for it =)
Excellent video!
Thank you! It was really well explained and easy to understand.
Very helpful and well illustrated. Thank you.
I thought this was going to be just like other videos I've been watching but nope, it's the best.
Great video and straight to the basic point. Thanks.
This is an excellent tutorial.
well, it does act almost like a short circuit when plugged to a dc source, but this is only until it is completely charged... I really enjoyed the video anyways, and I've been watching your videos and all of them are great and helpful. Thank you very much!
Nicely explained sir I learned a lot from this.Keep doing good work
Didn't have a clear idea of inductors until i watch this one. A very nice explanation indeed..
Nice explanation. Love your videos!
Clear, simple and informative. Make more, and show more changes so it is easier to comprehend the effects; e.g. first showing the 5mH inductor and then changing it to 10mH inductor, or something like that. If that can't be done, then explain why, or if it has no effect at all mention it as well.
Best explaining methode, *I love it*
Greetings from Indonesia
This 3 minute video taught me more than a month worth of lectures... I swear, the current methods colleges use (at least lectures) are inefficient.
FANTASTIC videos. thanks
Hey superb man continue the good job I like your explanation way
Welp, its going to be a long night, I have 50 videos to watch! This is great simple to understand content!
just what i was looking for really good video
Thanks
yesssss!!! just what i asked for, thanks afroman!!!
Excellent and clear introduction
Thank you for the explanation. .keep it up man!
Great explanations! Keep making more of this videos... ;)
are you an excellent teacher...please keep making vids, i am still waiting for the basic voltage and resistance videos ..i just saw your amp vid
You are waaay better than my circuits professor!
Im a freshman in electronics engineering and this video helped a lot with understanding the basics, i tried to read it a head in the text book and got confused lol thanks! :D
Mannn... the info was so smooth to ingest.. that's hw i dreamed of the education.
I could love this video .video really helped students to understand inductors
You are explain very good and deeply explain main purpose and work of inductor ,so your video is very useful
Very nice explanation!!
perfect explanation keep up the good work
Also, I clicked on ''Show More '' and I am now using your Amazon home page too !
And can donate later...
Quick question: Do you have any induction water heater plans ? I am interested in making a home water heater to efficiently heat our hot water.
Thank you, gk.
Way better than expensive college classes. As an EE student, Inductors were something I just could not grasp well enough.
It's because the magnetic field around the wire, adds up, when coiled into an inductor, this is what produces the back EMF
You're a genius at explaining! I finally understood inductance and filters.
Could you do a tutorial on the NE555?
Thanks in advance!
Ric
good to learn about inductors from you.
Another great video...
awesome, nice to see youre back. nice scope btw :P
bro you cleared my concepts thank you very much
very nice video and easy to understand
What a great video.
Really helpful.thanks buddy
Please do a video on Capacitor,really appreciate it
All of a sudden when I watched this video I realized how I could make a magnetic detector, for Arduino projects. Inspiration- you never know where it comes from! :D
Nice video!
Excellent explanation !!!
Thank you... very clear and nice explanation... !!!
thank you! really clarifies what and how inductors "store" energy
nice one, this is the simpliest and most illustrative video ever. Please what sought of oscillope app simulator are you using? I am a computer engineering student in Nigeria, I loved the simulation
Brilliant as usual
Thanks, very informative :D
short and precise, thanks a lot :):)
Thanks for your efforts
Thank you, finally a practical example.
suggest the best circuit simulation software in which we can design and analyse like you did in oscilloscope and Thanks for the video.
Dude, you are amazing..
This was brilliant!
Best explanation! Thanks a lot
Thank you. This is very helpful.
Great job narrating.
HOLY SHIT!!! Electricity is so cool. :O
Great video! Thanks
Many thanks - a little more knowledge gained towards my full ham license :) 73's M6TGT
fantastic explanation :)
So,
Capacitors are used to smoothen any voltage ripples in DC and inductors are used to smoothen current ripples in AC?
very good ,concept about inductors are clear now
thanks
hi, very helpful vid. you helped me understand that an inductor is to current what a capacitor is to voltage (right?)
at 0:30 you say energy (current?) is stored in the magnetic field. Does that suck current away from the output of the inductor? or does the inductor output "build up" current over time, as a cap builds up voltage over time?
does the arrangement at 2:57 demonstrate how a transformer works?
at 3:00, what is that high freq content inside each cycle of the square wave?
thx!
