Lesson 1 - What is an Inductor? Learn the Physics of Inductors & How They Work - Basic Electronics

[@iprofessionalamateur]

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.

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!!!

[@NoName-mr1lh]

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.

[@franciscoodgers3866]

@@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

[@uriel4829]

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.

[@MathAndScience]

Wow thanks so much!

[@bencyber8595]

what is education

[@Fadic4]

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.

[@LoveMyAbeshaWomen]

As an electrical engineer with 15 years of experience, this is an excellent explanation. I couldn’t have done a better job!

[@loverboy-if3ox]

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.

Glad for you! Keep learning, my lad. God bless you!

[@gratefulone5317]

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!!!

[@Ancipital_]

I signed up too. Jason is teaching me so much. I had an unfortunate childhood / schooling. Jason is teaching me a lot that I never had the opportunity to learn before. He's a true blessing.

[@marty7922]

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.

[@Mary-wk6of]

Thank you so much Jason! Excellent teaching!☺️

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 ❤❤

[@geelleguure8808]

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.

[@fransmurati2370]

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.

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.

[@rebeccafrost9933]

I've been struggling to understand inductors but this is a really helpful tutorial

[@echowenqi]

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!

u r seriously nice teacher.....thank u

[@arthurstuartleo1998]

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

thankyou sir, this video helped me alot to understand about inductor and gave me a feelings about it....

[@IIDECMNH]

Thank you very much, I just got the correct direction for Inductors .

[@carloshing673]

Great video .the dislikers have no knowledge of electricity

[@pl747]

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.

Thank you sir for such a clear explanation really appreciate it .

[@mr.technician4144]

Sir, can ask some question?....Because I am confusing of it....I mean how the current flow if there is no voltage as you'ved said? Because on ohm's law voltage is the force to the current to flow if there will be a difference since the inductor is connected to batt. And there is a difference current flow voltage pushes current to flow?

[@rupeshortega9680]

Voltage is a potential difference between two points: the other has more electrons than the other end the latter being less of electrons so it is positively charged like a charged battery. It is the attraction of these electrons to the positively charged atoms on the end of the battery that attract these electrons, right? If I put an inductor between the anode and cathode, and I put voltmeter across the inductor, no voltage reading? Are we not supposed to read the voltage between the anode and cathode of the battery? If no resistance against the inductor, is it not supposed the absence of voltage drop, but voltage is there exactly due to potential difference in the anode and cathode which causes the electrons to flow? I do agree that changing the amount of ampere flowing through the inductor makes the magnetic fields fluctuate and voltage as well, but kindly elaborate further the physics behind the absence of voltage when constant current is fed through the inductor. Lastly, is not all conductor innately have resistance which varies per diameter, length, and temperature? Thanks for your answers to my queries. Assuming we remove the battery, does not the energy stored in inductor reflect voltage?

[@keylanoslokj1806]

​@@MathAndSciencewhat are the real life uses of that part?

[@FesterPussbucket]

So one could compare the function of an inductor with the function of a flywheel on an engine with the voltage analogous with flexion?

[@guywhoknows]

Little bit confused due to error in terms If I increase voltage. If I change current. Volts and currents being two different things. Then expressing that the current change creates the voltage which is proportional to the current and the change of the current. So if you have 10 amp at 0 volt there is no electron flow thus there would be no field and no voltage created. It's only when voltage is applied that you have a flow and field. Surely voltage is the induction on the current to make the field and change the voltages, but does this change the current? (Losses) There is no resistance so no loss in ohm's law, however doesn't the field change cause a flux resistance?

[@TitofBee]

thanks a lot for this lesson

[@absolutezero9874]

Thank you sir. But isn’t V = L*d(i)/dt? The induced emf would oppose the change of current.
