You know I am an old fart who has haunted this old planet for more years then I would care to admit. I have been playing with electronics before the concept became even a bit popular, I cut my teeth on popular electronics and popular science magazines, garnered from the school library and with half their covers torn off by the local drug store (you recall the drug store, where you could get a coke or a soda and comic books right?) At any rate all this time I have grown up with the semiconductor world, and worked on the fringe of the electronic world in the military. That said, it was not until today that anyone explained so clearly that the bell in my head rang with understanding of exactly how inductance really worked. Sure I always knew that it did something to the electricity, but never really understood how a simple coil of wire managed to do it. Now I do, and for that I shall be eternally grateful. Thanks from the bottom of my heart.
same here bro!
"eternally" might not actually be that long going on your own description of self.
Not to devalue the video, but rather to encourage the continued hunt for comprehension of electronics, I will tell you that your ‘Eureka’ moment would have likely come to you sooner or later. I agree, and I came to understand the concept in a whole new, more comprehensive way thanks to this video, as well. Electronics is like language. I’ve been sort of pretending to understand and follow along in texts and in videos, and I’ll keep faking my understanding, until, one moment will bring clarity to me, and my understanding will just get this huge sort of promotion out of one comment, or illustration. One moment I have no idea what this means, it reads like a language I don’t understand, like Chinese, then, in that one golden Eureka moment, the whole thing comes together, and I have more thoroughly understood another concept, and that’s really the reward, the pay off for my continued efforts to learn electronics.
Jerry Ericsson Yup, this guy’s good 👍🏻
An inductor is a coil, think of a coil spring storing energy, not the same, but compressing then releasing. If you push an object against a spring it will adsorb energy, but after the object (electricity) is removed the spring releases its energy (current). The more weight (electricity) is pushed, the more the coil spring compresses.
An inductor stores energy via a delayed or impeded buildup of a magnetic field, which is an initial resistance to change - This concept is used in oscillating circuits designs.
Does it effect the volts?
I have watched several videos on electrical basics and have found yours the most helpful thanks for posting!
Whoever you are, I deeply love you with my whole soul.

Wauw awesome. Im homeless and trying to learn repair to get a job. Cant do any heavy lifting anymore but i can not afford course or books. So im very very gradefull for this teaching. Thank you sir. Subbed and liked.
Sir I always like the way you teach us with your sufficient tutorials for electrical component.we usually benefits.
this is amazingly good... all the info in the video... showing the rates of current... everything... a picture and your explanation.. are super.. god bless.. thanks
Ur videos are simply awesome. Keep up the good work
Clear and understandable. It's easy once you know how. I guess you just need the right person to explain it well. Many thanks brother 🤗👍
Loved it...so beautifully explained
Great explaination about inductors.
Thank you !!! So much !!! I subscribed ! Eazy to understand and just great ! Thank you !!!
Quite understandable & Enjoyable, Thank you... Love to see more
Neat explanation. Good work!
I like your work it's Short n well explained , keep going plz
from now on i am your fellow thankyou for your amazing video
Excellent video. Thank you.
superb...sir....i really understood
Great video thank you for shearing all this knowledge !
that *
Explained is as minimal time as possible. Great vid! (It's a backup for power loss)
Sir great job thanks for explanation
Thank you for the video!!
Come back! I love ur vids.
Very well explained! Thx
hi there, i watched and continue watching every single video of you from the start to the beggining and i can really say that it helped me a lot with my projects and i would like to say you a thousand times thank you for this, now i'm dealing with a simple boost converter circuit surely without all the chips and the op amp and all the complicated stuff, i scavenged some electronic components from a variety of tvs printers and all monitors like that but i have a problem with the coils, so i'm asking you if you can make a video about the mathematics behind it in order to, for example, make and inductor with an average uH precalculated, what is the relation between the numer of turns, the thikness of the wire and the length of the solenoid, and how does a ferrite core can change the value of the inductance, and again thank you for your videos you're amazing !
thank you excellent video
but its doing same thing like a capacitor ?
Very clear.
Thanks a lot
Love this! Thanks
Excellent video, very well explained, thanks for that, could I ask in principle I comprehend the 10 vac per, ingoing. Rise to say 100 vac out going, ... But what of any amperages, in / out expected... Changes ?. Thanks again ... Thom in Scotland.
How did you generate the signal to turn the mosfet on and off?
What frequency did you use?
Pity you didn't show the full circuit.
Does anyone know the application program he is using to create this circuits? I really like how this program is set up and would like to use it to view other circuits !!
Nice video, what program is it you are demoing this on
Hello, thank you for this video. I am trying to hammer these concepts into my mind, little by little. I know little about electronics. One question slightly off the subject: When the transistor is on, why doesn't the current split to: 1. the transistor and 2. the diode as well (just as in any old regular parallel circuit)? Thanks to anyone out there for your answer.
The inductor induced a voltage correct that forces the current?
Is the continuation of this video already out?
Maybe you’ve done so in another video, and maybe there’s an easy answer to my question, but I’d recommend discussing this topic if you agree that it’s really lacking attention on the usual channels. So what is a Henry / or a milliHenry, and why is it called a Henry?! I know I can look it up to find out, but to hear someone lecture about it makes it more interesting and even more understandable. I’m curious about the Henry(s)!? I don’t even know 100% whether I’m correct in calling it a Henry, so please consider this as a short video topic, or tie it in with another project video? Thank you, the animation slides are great, and the visuals go right along with the speaking, it’s great!
Not a bad vid, but you spent more time talking about the next videos than you did about voltage which I don't think I heard you say once.
What stops the current flowing through the diode all the time? Or is that something to do with how the MOSFET works.
Hey there, it makes sense why the current through inductor doesn't fall down to 0 instantly after opening the switch. But why does the current doesn't go to max instantly after turning the switch on?
An analogy always helps and the inductor is the flywheel of the electronics world, is it not?
what software is used to simulate the boost converter?
Can you discuss about op-amps?
Hi. So the inductor increase the voltage and current in the circuit ?? this I want to know from low input to high output??
Thanks
wouldnt the inductor generate a back EMF with current flowing in opposite direction?
At what part the inductor's current flowing in the opposite direction?
which software is used simulate the circuit?? its very nice and those study electronics its useful
Ahmed Saam Interested
For the above to happen the inductor must be made up of Soft Iron right?
What program do you use for this simulation? Thanks.
Yes I was also going to ask what simulation software was being used?
Im pretty sure it's everycircuit by musemase. I could be wrong though. Either way it might be useful to you.
Just out of curiosity, why the current does not flow through the capacitor when the switch is on??
What is the purpose of the capacitor in this circuit?
The bemf current spikes passing though the diode then into the capacitor is like electric motor that could charge it self or another battery separate to the this circuit. Why dont electric car have this circuit to have longer run time?
How is the output voltage useful when the current is reduced
Harikasın patron.
Wow I now understand (thumbs up)
So what the important role of the transistor in this circuit ?
looks like a DC to AC converter. thank you so much for considering my suggestion. also id like to ask of you can explain (like you always do in best way) some 78xx parts... like 7805 if im correct that turns all dc voltage to 5V (dc)
+Destan Kadiri it's actually a dc-dc boost converter. But dc-ac is still on the list. Yes I also have linear regulators on my list too :)
7805 is a voltage regulator it will do its purpose of providing 5 Vo however how long can it withstand its thermal heating capacity? For that reason we use DC-DC converters for better efficiency and easy switching with MOSFET controlled regular pulse activation. Just like a Transformer in AC circuits, these kind of DC-DC transformations r used like ex: Boost, Buck or Buck-Boost converters.
Do u plan to make a video on transformers?
what is tthe app that you are using?
,what happen if you let the switch is opened all period , don't toggle between on and off on other the hand why do you used the switch?
Will it effect a circuit if it doesn't turn on & off?
What would happen?
what is key difference between capacitor and inductor as both store energy and then deliver
Capacitor: Stores Voltage Inductor: Stores Current
Just like a tattoo machine minus the diode. Thanks for the breakdown
Thanks but don't understand why there isn't current flow from the power supply but the inductor when the switch is off.
power supply have 10v 1 amp, inductor make max 8 amp it is like don't late low amp pass .
What is name of program used in video?
Everycircuit is the software
hmm why is the current coming from the 10V when the transistor switch is off?
it will be help full if u teach the working of resistors
I already have a video for this
Love it, currently studing electronics and your videos are beautiful.
perhaps you could approach with some more of the mathematics behind rlc circuits ,
Deviantfulness He's only talking about the basics, he does a great job. He definitely knows what he's talking about and I guarantee he could talk about rlc circuits. The thing is, inductors and capacitors work different using dc vs ac. I'm willing to bet the rlc circuits you're studying are connected to ac? In AC the easiest thing to remember is that an inductor acts like a resistor. The phrase "ELI the ICE man" may also help you when figuring out when voltage(E) leads or lags the current(I) in a capacitor (C) and inductor (L)
What does the 500uH on the inductor mean?
welldone
Thx 😃
What is the software you are using?
Everycircuit.com
Question, so whats difference between an inductor and capacitor? Im confused
what this software?
what software do you use
Its called EveryCircuit and it is awesome. $15 for the full version, but its very worth the price in my humble opinion.
Could you back it up with equations?
How inductor doesn't allow sudden change in current?
Thank God for British concision.
Isn't the diode pointed the wrong way? I was always taught current flowed into the point of the diode.
Do the follow up video
Could this not power itself then after initiated?
maybe in a nonresistant circuit
So, what is the difference between a capactior and inductor for functionality then? They both result in dissipating charge (in different ways). Why use one over the other?
Perhaps I'll do a video on this. I'd have to write a huge paragraph to explain this.
Both capacitor and inductor are used and called storage elements. Capacitor stores charge in the form of electrons while inductor stores it in terms of current as it slows it down.The current( rate of change of electrons with respect to time )flowing through the inductor will create a magnetic filed that will oppose the flow of electrons until it reaches the maximum storage and that is related the number and length of coils.
In DC circuits the inductor will charge and behave like short circuit and capacitor will behave like an open circuit because there is no opposing force to change the direction of electrons from one plate to another.
I hope this answers your question!!
A capacitor stores energy in an electric field, an inductor stores energy in a magnetic field.
Will agree with you this is simply electronics rather than a thick text book with no clear explanations
What will happen to the inductor if we continue flow the current to the inductor without turning it off
I found one difficulty in drawing graphs of sinusoidal main field flux due to source , lenz's flux that opposes changes in main flux , and also thus effective flux in inductor and thus the emf graphs, when a pure inductor is connected to an AC sinusoidal voltage source.
Can you please upload them.
Is it possible to connect single hyper voltage coil to the atmosphere and Grand in every circuit
how are choppers applied in motors
If you take a look at my transistors video, chopper transistors essentially work with the same method, although instead of controlling the brightness of an led, they will control the speed of a motor. Perhaps I will do a more in depth and technical explanation in a future video.
So...
What's an inductor?
You explain so much
I wanted to have one sentence
Does it make current go fast?
hahahaha, same feeling
nope. what it does is simple, you see if you set up current through it using a battery into its steady state and switch off suddenly. the magnetic field in it will collapse, or in other words reduces gradually. how ever the reason for gradual loss is explained with faradays law. faraday explained if change in current is occurred that will give rise to emf. this emf is to maintain the magnetic field as this follows current will generate through the coil if its sinked in another path.
An inductor is just a coil of conductor wire.

what the app for making animation in this video?
indoAink every circuit I think. If you haven't found it yet
everycircuit.com/
It can run on a pc / laptop on Chrome only or Android device or (Apple - I think)
nice
Good
a list of all components used
Just like a ram pump for water, except governed by an external timer.
So by passing electricity through a coil of wire making it have a magnetic charge it turns the magnetic charge into extra electricity when you stop the current?
When the magnetic field through the coil changes, a current is induced. I think it has something to do with Lenz's Law, not sure tho.
Tq
If anyone is interested in electronics the greatest results that ive had was with the Gregs Electro Blog (just google it) definately the no.1 course i've followed.
👍👍👍🌹🌹🌹
i have that software in my phone is soo good is free for a day after you buy it. for pc is it free? . but is epic worth it every peny . everycircuit you can find it
What software
can you give a practical example how this is used in real life ?
Look at your PSU or PC motherboard or laptop motherboard..
I still don't understand.
Current passes, creates an MF, which collapses if no current is flowing, because of the switch, which allows the current to flow every other second. Current is not flowing -> MF collapses -> release current. Isn't current flowing before? Or does current rises because the MF collapses?
