- Learn what an inductor is and how it works in this basic electronics tutorial course. First, we discuss the concept of an inductor and explain the physics behind how the magnetic field inside of the inductor coil can store energy.
We then discuss how the voltage across an inductor is proportional to how fast the current through the inductor changes. We close by discussing how the magnetic field is concentrated inside of the inductor.
In this electronics course, we cover how an inductor works and how to use inductors in circuits. We explain how capacitors and inductors are closely related, and how to use inductors in electric circuits..
I have never ever passed maths In school and could not even solve simple equations. It was a disaster. 2006. I finished school and could not get into college due to the absence of maths. The supplementary exams I took was a failure too and I gave up. Until I came across a DVD series titled Fractions through Algerbra in 2014. Thats when my eyes opened and it all began to make sense. Today I am in my 2nd year of Electrical Engineering and Salute the MathTutor for opening up my mind. Much Respect. Keep up the Good Jason.
Kidzo900 congrats bro may God be with you at all times

Wow, I just read this, better late than never :) I am very, very proud of you. So awesome - stay in touch and good luck to you!!!
Things don't always make sense immediately. Perhaps it just takes longer for some people but I think it depends on the quality of the teaching. Concepts weren't always clear to me when I was a student but became clearer later. Good luck with your work.
@@MathAndScience just wanna thank you for the GREAT explanations and examples! Been watching your ohms law and resistors videos. They are REALLY helping out!! Thanks.
Jason explains everything every mark on the board every detail, a gifted teacher
As an electrical engineer with 15 years of experience, this is an excellent explanation. I couldn’t have done a better job!
There are very rare moments that I have throughout my education when I look at an educator and think "this is why I'm going through this". It is an absolute pleasure to hear from these people.
Wow thanks so much!
what is education
sir, I have a learning disability and this has helped me to understand greatly. I'm starting to slowly understand. god bless you and will continue to study with u.Thx a million. Keith.
2 years late but I had to say, I love hearing about that drive. Don't let anything hold you back, keep learning!!
Glad for you! Keep learning, my lad. God bless you!
The best video to explain the induction in the intetnet of thousands of thousands of explanators
This is fantastic. I love math but had trouble understanding inductors. This guy does an amazing job of putting detail into allowing a mind to learn in its way.
I am extremely grateful for how gifted you are at explaining these difficult concepts. Thank you for sharing your knowledge and making it possible to understand the why and how. I’m currently in a mechatronics program and find your explanations extremely helpful. I signed up for your math tutor membership and it’s the best investment that I’ve made to support my education goals. For anyone that finds these videos valuable, I highly recommend the membership. You will be amazed with all the available information on different subjects to support your education goals. Thank you!!!
Seems like i have learned the basics of electricity from your videos what i was trying with 4 years from books :) Thanks a lot from Hungary!
i love this guy. He is the best, i wish he was my professor for all electrical engineering classes, i have not seen a single person explain physics and these concepts as well as he has. i wish i would've found out about him in my first year of college, i would have graduated by now.
Sirr I was gonna quit my computer system engg and go for software but thank god I came across ur videos and now my concept Is clear about circuits...u just saved someone ❤❤
this is my guuuuyyy! ive watched almost all of his videos and ive understand all of it. i recommend watching his vids about different kind of circuit
11:40 I like this guy's writing / diagrams, but that letter i in particular is excellent. Might be one of the best freestyle i's ever.
The voltage ( V ) under the Line is also superb !
And he even extends his pinkie finger when doing it. :-) JJ.
Amazing, earth shattering, mind blowing , never done before, spectacular, magnificent, one in a million
dont change the way you structure your lessons,on point allways,and at the right pace,i like the way you drill concepts in
to make us sit up and take note,its not repetitive,its neaded,i can listen to you and not get boad,because i leave with new
knowledge,thank you so much.
I have been trying so hard to understand this inductor for long thanks I finally made it
This was so helpful. Thanks for breaking down the concepts , much appreciation from London!
Voltage difference across a straight wire and an inductor (coiled wire) is 0 with stable current.
Voltage difference across an inductor momentarily lags behind current change.
Current fluctuation produces inductor oscillation, and inductor oscillation emits electromagnetic pulses.
So much to learn... hope this helps some folks, thanks for the lesson.
Sir, I truly appreciate the manner in which you're imparting this basic knowledge of electronics. It's the emphasis that you make on the salient points of the induction concept that any learner needs to remember, that renders your presentation captivating. Thank you.
thank you so much, I finally get the influence of current on inductance!
There are people that are human, and have human feeling, like this guy. He learned modern knowledge and now he is passing his expertise to us through U-tube. Everybody is benefiting without going to school. He is blessed and U-tube owners are blessed. Sir keep going the nice job and educate our people in this earth, white, black, brown, yellow and red, no matter about their color, origin, culture etc. as long as they are humans having two eyes, two arms, two legs, a head, neck, belly they are your brothers and sisters in humanity and all of them are going to bless you. God make you a great man.
WOW ! BEAUTIFUL, GIFTED INSTRUCTOR
amazing video, this guy explains everything in a very simple and easily understandable manner.
Let there be light! Excellent video, thank you very much sir!
thankyou sir, this video helped me alot to understand about inductor and gave me a feelings about it....
Thank you for a clear and concise introduction to inductors.
Bravo
Wow this is the best explanations. I with I could like it 10x
I learned more from you in this
25 minute segment about inductors form you than in my whole semester in circuit analysis II.
I’ve rewatch this whole video.
Thanks!
Thank you sir!
Thank you thank you thank you. You are the best teacher i find. After reading inductor for so long,now i know whats going on. thank you
Just discovered this video. This guy is an amazing teacher. Much respect.
Thank you for your explanations.
Thank you for all of these videos that you post here. You are a great teacher with the ability to make alot of this information easy to understand. Thanks again!
You sir, are a life saver
I have never understood a teacher as easily as I understand Jason. Honestly He explains very well.
Thank you Alberto!
@@MathAndScience Thank you Jason.
Now this is awesome teaching. Very inspirational. Excellent work, Sir.
I wish you was my tutor when I was studying Electronic Servicing in Birmingham UK.
Absolutely brilliant!!!!!!!!!
I love these videos! I don't understand everything but what I do know is I am able to learn something from everything these classes teach and at some point a light is going to go off!
Appreciate your efforts in such beautiful explanation. Thank you is all I could say #respect
Thank you Professer I'm following your material. You aptly great. . And your .cominucation is processed....
Quality explanation. Thank you...
I am so proud of you. Out of millions professor , you are the seed of genius on this earth. Thanks to youtube again.
Thank you so much, Professor, for help
Excellent Video Instruction of Induction lesson. Great instructor you are better than many EE professors in many colleges. Thanks
Thanks for making me understand some concepts that I was ignorant to
Sir ur the best teacher to teach so clearly and in detailed manner that i hve come across so far. Thanks a million times and god bless u! Please keep uploading more stuff.Frm srilanka 🇱🇰
I love how you teach in the simple way , I’m interested on learning more from you
you are the best teacher and explainer in this world. I do not know why i do not get tired when listening to your lecture.
Great explanation. Thank you very much!!!!
thanks so much ,you do articulate so optimal you are blessed with great knowledge
Thank you for post this video onto CZcams
You taught amazing..tnk u
Thank you so much. I am a retired Radio ofiicer and I have the oportunity to watch your useful electronic lesson in English.
I agree- you are a good teacher. Well done!!!
Thank you very much, I just got the correct direction for Inductors .
we like him , a perfect professor from a uni . as good as professor 李永乐
.. cheers ..
You are a really good teacher and can make complicated knowledge easy to understand. Just want to ask whether you have any plan to make videos about the power system stability or generator knowledge since you are an Electrical Engineer?
This guy is a really good teacher.
Finally, an accent I understand.
Best explained sir thanks alot
thank you. you're the man.
Thank you for the video. I have a question which is about when you say "increase the current", do you mean increase how fast the current change or you mean increase the amplitude of the current? If you say "di/dt" is how fast the current changes, then why it is also related to the amplitude of the current? Got a little confused. Thanks!
thank you may God continue to bless you, you have opened my mind when you talked about how capacitors and inductors can be used interchangeably in circuits depending on the goal of the circuit,say if i want handle the energy in the circuit like a microwave circuit that requires electrical energy to handled so that it can be converted into heat energy to warm food stuffs,a capacitor or an inductor can be employed to perform that function,and also in transmission of radio waves ,sound energy needs to be handled in form of a magnetic field or electric field in order for it to be transmitted ,thanks for understanding what you were taught
Sir i thank u so must.now iam start to confuse about the inductor and resistor
amazing explanation!!!
Why didn’t I run across your channel sooner? You explained it so well. Will start to watch all your other videos.
Wow happy to know how physics is key behind this. Just wow. Thanks for this great video
nicely explained 👍
u r seriously nice teacher.....thank u
Yes! thank you! I'm finally understanding this.
Awesome!
Jason, MathAndScience.com
Thank you sir for such a clear explanation really appreciate it .
Having looked at many tutorials, this is the clearest explanation I have found. Great instructor!. thanks
Easily understand the concept thank you sir
Another great video. Thank you!
Thank you so much for all the videos, I learned a lot from them b4 I go to school.
I really appreciate it!
Jason, MathAndScience.com
great instructor and gives the students confidence
I've been struggling to understand inductors but this is a really helpful tutorial
Very well explanation . Thank you so much!
sir you saved my semester💜
Awesome, good luck in your studies!
@@MathAndSciencewhat are the real life uses of that part?
For Visual learners, it wiil be important to see a reality example of an inductor and 1 or 2 examples of where it is being used, asumption that those that watch your program knows what it is. Work from Reality to Symbols to Explanations. Your explanations are very good and I will definately subscribe as a early hobbiest.
sir, thank you for coming across your video.. it's like an accident that your video appeared on my youtube wall.. i am fascinated with science and technology like electronics..your tutorial is very helpful for begginers like me..
Thank you very much sir your lessons is very clear and easy to understand
Awesome man!! Great explanation!
such a good explanation! Do you have any blogs?
Can't thank u enough am at it "Electrical Engineering'
Thanks I am still trying to grasp this system but I have learned more than I ever knew I'm a freshman I am still very green!
Thank you so much.
u are the best
Hello sir. Your videos made me understand what curcuits was all about. My request, can you upload also some tutorial of Electrical Machines?
So one could compare the function of an inductor with the function of a flywheel on an engine with the voltage analogous with flexion?
Excellent!! Thumbs up Sir!!
Thank you for these great videos
This video is fantastic. You take your time that many other teachers simply don't. That made me want to see more of the videos you refer to.
The only unfortunate thing is: your naming system is not intuitive. Please just include a link to a playlist where this video is part of, and the other playlists you refer to.
This is really really good!
Bro now i understood why we wanna learn abroad. The professors we find in our area they dont even know what is a di by dt mean just they say us its a formula u have to bihart it😭😭😭😭😭😭😭😭😭😭 your a life saver
Good work
Thank you sir I enjoy your teaching
sir you are awesome
I wish you would use a welding circuit for an example. Like when you strike an arc the the current will increase and the inductor will supply an increase in voltage to make striking the arc easier and since the current is always changing a little once the arc is struck the inductor will help maintain and steady it by increasing and decreasing the voltage. Giving a correct size for the inductor would be great too.
Does the current direction also change when you flip the polarity of the voltage to into account a decrease in the rate of change of the current???? You said you fill the sign of the voltage for decreases in current rate, so then, to keep the passive sign convention, don't you have to flip the direction of current as well?
thank you sooo much :DDD
The unit of inductance is the 'henry' (lower case h). Upper case for the symbol (H).
