I've learned more about electronics on this channel than I did in physics in college.

Mr GreatScott! I have a physics exam tomorrow and it's all about coils and lens law and I think that God had sent you to rescue me .

I love how you explain about this, my teacher always explained to the classes like spelling a magic. After he finished spelling, i dont know why all the students like got amnesia, even me.

You have no ideia how rare is your video. Simple and directly to the point. I mean rare because I'm watching several videos and very few explain right.

I'm studying to be an engineer and this really helped me visualize what they taught in our circuits class

That info about the human body generating a 50 hz signal blew my mind. It cleared so many of my doubts!

Thanks! This was actually a VERY helpful video. As a beginner in this area of science, I am very grateful for the thorough explanation and example. Thank you.

Your English is better than my understanding of Electronics. I Know Nothing! Hogan! ;-)

Best explanation of inductors on youtube imo! It helps if you think of current as a slower version of voltage.

when you talked about how we have a field in our bodies bc we act like an antenna it made me think of something i realized as a kid, mp3player's that have a radio option but require headphones to work the radio use your head as a way to get signal. i found this out bc slight twists of my head could make me lose signal to some stations. i thought it was cool. you could even boost signal by touching the earbuds with your fingers.

I wish this video was LONGER you do such a good job.

Just want to thank you for the videos, find them entertaining and educating. I'm in my thirties and haven't done anything with electronics since I was in my mid teens as I've been on the programming side. these videos just nicely click my memories back into place.

I really appreciate what you're doing man I believe a lot of people might be also thankful for what you do please keep it going!

A very clear and concise video. A great job of explaining the function of coils/inductors.

Big thanks for all this Scott, I stumbled upon you and now look forward to seeing more, keep up the good work.

Great explanation, keep making these videos!

Man you are awesome I can't thank you enough. You teach the electronic much better than my high-school teacher, and you have great equipment over there. Thanks again for the all of your videos. Waiting for the next one.

I can't believe i finally understand what these coils are for, thanks for a great and easily understood lesson!!

You have a gift for explaining things. Thank you for everything.

Thanks for the many great Screenshots, very comprehensive.

Your channel is probably the best electronics channel on UKposts :)

I just watched 2 of your videos and subscribed because I actually understood this one, and it helped me understand a lot more about the tools I use daily in SaaS. The other was the explanation you gave on salvaging parts. It was like (a summary of) a book summary on what is inside of those things, for us non-hardware folks.

thanks really helpful you've given me the chance to learn about my hobbies on a deeper level

I really love your tutorial! Thank you so much!

Thank you for sharing your knowledge on coils with all of us....

Your videos are the BEST on youtube !

Yes, your info videos are so helpful! Thank you!

What an excellent channel. Subscribed and Liked.

Thanks for the info. In all of your videos you explain really well :) Keep up the good work!!!

You are an excellent teacher. I know a few EE's who doesn't know anything in comparison with you.

Awesome video!!!! Thank you for breaking everything down into lamen terms.

I din know someone could make a someone what mundane topic so interesting. ... Simply fantastic, great scott is awesome

i am studying for next year engineering xams and these videos Really help me understand why and how these things works keep it up

great video. lot of info I was looking explained in such a short video.

Ahhh u briefly mention boost converters in this video. Even that small diagram helped solidify what I understand about them. Thanks!

you explain better than my teachers thank you thank you thank you

Truly Great Scott , can u please make detailed videos on BOOST , BUCK , and BUCK-BOOST converters

So glad you're doing your electronics lessons again!

Nice and informative! Thank you.

Best video on explaining inductor and its application

AWESOME EXPLANATION, .THANKS FOR THE VIDEO.

GreatScott! Amazing video please keep up the good work!!

Okay that intro is awesome very unique and cool

nice tutorial, now I can continue building 9v to 12v converter thx.

Excellent. You've got a great channel. Keep up the good work.

hi, what can we do with the high voltage transfos (found on switch power supply) ? thx

Love this video! I always wanted to see on a scope what happens when you vary inductance in a circuit. I wish I would have seen this video years ago when I was in college. thanks. :)

I want to connect my 12v dc motor to a adjustable plug in power supply for purposes of making a small lathe(ergo the engine load will be high when applying chisel to wood). Do I have to use a fly back diode like shown to protect the coils of the plug in trafo?

When I was a little kid i would hook up a 9v battery to a coil and when I disconnected it i noticed I would get shocked. So I added few wires to end of the coil. Had some handles to ends and had kids at school hold on to them. So they would get shocked when I turned it on and off. It was quick pulse nothing to painful. Just fun and games. This makes sense now. Later on I used a 120v wall adapter transformer and had it the opposite way. Added a small Dc motor so it would turn on and off really fast. So if you held on to it. You would not be able to let go.

This was very helpful!

Dear @GreatScott! so is it safe to assume that it never hurts to have a flyback diode at the ends of every induction coil we make at home no matter the use?

thanks a lot for this awesome videos with good demonstrative explanations

Great explanations. Thanks.

great job man i following you from egypt

Why I didnt had an electronic teacher like Great Scott in College?INspiring

I love your videos a have inspired me to do what you do.

good as always GreatScott!, good as always.....

resistance is futile.

hi greatscott your 5v step up converter uses mosfet but if i use transistor can it will work

Love this guy's accent!

Great teaching. Thank you

very good way to explained. Thanks.

Great Scott is really great!

Another great video especially like your DIY bench power supply which I am trying to recreate using a 10A 12V input supply,should be good when finished 😉

I really in love with ur vdos

Deine videos sind sehr genial, vielen dank

Hey I love your videos!!!! Do you post your notes that you have in your videos?

Well, hmmm, I understand most electronics on any circuit board, I was very excited to see you doing this one on coils. I still, well you lost me. I'll watch it again. I wish you had given an example say in a common circuit like a small amplifier, and show the difference with and without the coil. Also what is the difference between a coil and a choke? I need to watch this again.

Great explanation. I develop training videos and you have given me some good ideas. Thank you.

Thanks Great Scott

Would you make a video about measuring inductance or build a inductance meter? It is really useful.

Do those standing coils with a ferrite core like the one at 2:48 crate a magnetic field strong enough to pull metal or a magnet?

Thank you 🙏 Very helpful

I love your videos! Fantastic..

1:42 is one of the biggest mind blows I've had in a while

+greatscott I'm looking to build a simple circuit for an automotive application. In some vehicles, when you shut the doors, the interior light fades off rather than just going flat off. I'd like to incorporate this feature into my pickup truck. Considering all the incandescent bulbs inside have been replaced with LEDs, I don't have to deal much current. I'm thinking a beefy capacitor or two may do the trick, but I'm sure it's more complicated than that. Everything is for some reason. Do you have any suggestions?

Great video, thank you!

Back when this video just uploaded, I was studying grade 7. Right now I'm 1st year college and come back to watch this vide again xD

Tell us more about radio frequency. Maybe building a very cheap Pocket radio?

Very good video. At 5:48 what is the way where the current flow ??

Best channel ever

Very clear. Subbed!

Thanks for information. But can pls tell me from where can I buy the inductor??

I like the water analogy for inductors: A water pipe with a heavy (flywheel-like) turbine put inline. It takes some work to get it spinning, but then when you disconnect the input - it still wants to spin for a bit. If there is no output path - the pressure will momentarily rise as the water is "kicked" by the inertia of the flywheel. Water pressure=voltage, flow speed=amperage, water volume flow rate=power, pipe diameter/flow impedance=resistance, static pressure needed to open 1-way valve=forward voltage

It is really useful for me.thank you

i like this guy's tones. pretty

You're an excellent teacher! Thanks for sharing your knowledge. Your English is good too! What is your first language?

Is there a realistic way to build a step-up/boost converter that is able to boost 12v up to 350v/400v without a transformer? and how complicated would it be to get a coil that can do this step up with an input current of around 50 to 100 amps? (or is there a way to use multiple like "25a" coild i.e. for such a project?)

What's a good website to get inductors I'm looking for some big ones in CRT TVs

great channel! thank you very very very much!

your lc meter is f** awesome !!! good video !!

Great Scott, help. I am trying make a boost converter, i am using a 1.2mH inductor and PWM from arduino, but i dont know which frequency i have to used, because if a use a low frequency my inductor gets saturated, and if I use high frequency the wave form gets distorted. Help

Nice video! Could you think of making a video on how to make a robot that follows you?

You're a genius!🙂👍🏻

5:51 The inductor before the capacitor ? 5:55 Should the inductor be placed before or after the capacitor ?

a nice teacher gifts

what is the music you use in background of your videos ?

5:27 I think it is "When the transistor switch opens" instead of "closes". Right?

So, could you use a (smd) inductor as a small magnet?

u helped me a lot thx !!!!!
