Here we are, nearly 6 YEARS after this was posted and it's still as good if not better than many of the other informational/instructional videos out there.
I can make a loud horn with an electromagnet a capacitor and a diode and a tiny needle it works by the capacitor at the wires and a diode going to the electromagnet. The needle is taped or screwed in place when power is applied the electromagnet try's to pull the metal needle and the screw pushes it back down and it repeats it super fast on the sound plate and it makes an Anh Anh sound
+RenaissanceMan929 You'd be surprised at how good instructional videos of the 50s are. For example, learning how a differential works.
RenaissanceMan929 is this guy alive and kicking today? I hope he makes more.
mohamulator I too love old film documentaries on science. I watch those on mechanism, electronics, chemistry, etc.

Collin Cunningham is an absolute legend, keeping the pride alive!!!
this is the best explanation of Inductance that I have found so far. Now I understand why transformers occasionally threaten the city
11 years! Omg, time flies so quickly!
Teacher: Since when did you become an expert in electromagnetics?
Me: Last night. LOL
Thanks, although I've studied electronic technology, as a hobby, for some 30 years, I really appreciate the work devoted to explaining the basics in these videos. The older I get, I find that my memory sometimes has a tendency to color the facts and it's handy to have simple explanations, like these videos, to see through the fog of age. I wish these were around when I was younger. I'm glad younger students can cultivate their electronic interest through such a obtainable media.
Excellent video! The teacher assumes that the viewer doesn't already know the information. Ideas are presented in a straight, relaxed, and down to earth fashion. An effective presentation!
Collin is the Carl Sagan of circuit components
Brilliant! The oscilloscope visuals finally made me grasp why audio equalisers using inductors attenuate high frequencies!
As an instructor of industrial electricity, I appreciate your presentation. Clear, lay terms and easy to follow. You paint a clear picture that anyone of my students can understand. Thanks for the videos.
Colin is just extremely good in explanations. Loved his tutorials and funny explanations. Of course his humor is always on good level! :)
This video was made 13 years ago and yet one of the best one I found on inductor. it's always the old videos : )
back in mid 70s at my junior high school, I met a guy named Scott who presented me a cigar box and encouraged me to push the button....an eerie long whine emanated out of the box to my delight...and Scott lifted the lid to reveal a circuit that he had built himself to maker the noise....we became great friends at that point
Word this dude needs to be on TV
he already was, way back in the 1970s no less - ruclips.net/video/bTrME5Pnft8/видео.html
3:35 bass snuck up on me like a ninja. awesome vid as always.
There's something very pleasant about this guy's personality.
love the hypermobile self inducted facial movements.....good job cc
All I can say is, I love the hidden humor, history and simple explanations. Best learning experience yet. keep up the great videos.
We love you Collin, make more videos!!
a very good video to start learning electronics. very useful info and nice drawing and colouring of that transformer
Good stuff, very well explained - with one exception...
if the current flow is instantaneously interrupted and the field collapses, it causes current to flow in the reverse direction as when the inductor was charged....known as counter emf. I don't know if that detail was left out for ease of understanding, but I couldn't let it go - Thanks for posting these videos, they're very good at getting the concept of how these components work across in an easy to digest manner.
Wow Colin, your explanaition of electronics is not only more detailed than my physics lessons, but also more fun!
i have worked as an electrical fitter for 3/4 years biuling power electronics for trains. thing is i have no idea how it all works... this REALLY helps. thank you very much (by the way yes is do know what im doing, just no understanding of why)
Great vid, definitely going to do that with the kids this School Holidays - time to break out some old 18650 cells
1 boring class= 1 hour
1 very cool and very informative video= 10 minutes and 46 seconds!!!
this is actually one of a complete details of tutorial in electronics
9:20 The "angry transformer" LOL :-)) Great video ****
your videos are amazing the best I have ever seen thank you very much
This guy taught me in 10 minutes what my professor at UNIVERSITY OF ILLINOIS @ CHAMPAIGN couldn't teach me in 2 lecture classes! (College of Engineering!)
Thanks Colin your videos are really clear and interesting. I'm learning about a new world.
Maybe sometime you should do a really small project like designing a led circuit with us and showing
how to put it together
i like the way he puts humor in his video's; it make's them original and significant ^^
9:55 "both of them... conducted... experiments" 😂 don't know if it was random or not
It was. Most of his videos have very subtle puns and references sprinkled throughout that he doesn't point out. They are all pretty clever.
like what other ppl said, the electronic component videos r awesome. the theme music is great. keep that
this is a great video. as you can see on the scope how the square wave turned out after it passed through the inductor and how its shape was changed. this is due in part by when current is first applied to an inductor, it is at its maximum and slowly diminishes because of saturation. Capacitors are the exact opposite they are at minimum when current is first applied but then they gradually build up to the potential.
thank you for your teachings bro now I feel confidence in electronics and civil engineering
These videos are some of the best best tutorials I ever seen. Excellent!
Thanks for posting them
I am an electronics student and i just wanted to say i LOVE YOUR videos they are helpful
Man, what a simple explanation/demonstration?! Thank you very much for sharing your knowledge!
Fantastic explanation. Found your videos a couple of weeks ago. You are a really, really good teacher!
i like your video style sir. after 7 years i find a great teacher for myself in physics with such of these experiments. I am thinking that now i understand well about electronics.thanx Alot sir
The best Videos With Relevant Information Here.
Dude, I must say you are awesome... love the lil oscillator...Keep up the good work!!..
Colin please post more videos you are better than my teacher
Collin made me get into electronics. Like someone always says on every video you have on here.... YOU NEED YOUR OWN CHANNEL!
AWESOME!!!
we just did this in my EE class, but still a great video!!
I like when Agent Smith teaches me some Machine-Language! "Mr. Anderson! You and your inductance coils make me very Henry!!"
Need more videos from this guy
I love this guy. Please post more electronics videos.
Great video!!!
Actually, our teacher showed some of these videos at school. It was awesome.
awesome informative video - way more fun than sitting in one of my old electronics lessons
Good clear information, its good to see how the simplist of objects can ammount to a massively useful practice!
I love these videos!
Its been a while since you guys have had a MAKE Presents...
These are great!
5 stars
Thank you for your brilliant, its the first bit of electronics I've ever started to comprehend , I will be subscribing and following a lot more of the videos. Far too many youtube videos have awful back ground music and narration that is far too fast to keep up with late knowledge gaps or jumps, so thanks again for making it easier to follow.
Dude, awesome video... I didn't know it was that simple and yet so effective and useful!
Awsome presentation skills!! Great work Collin..
This guy is like the Alton Brown
of electronics.
He looks more like the Stunt Double for Mr. Smith in the Matrix.........LOL!!!
Very clear and logical explanation
I just want to say that you videos inspire me to become an electrical engineer :) thank so
Cheers
I thoroughly enjoy your videos and think you do an excellent explaining things in a practical way that is easy to understand! I look forward to thatching more of your videos on basic electronics and their functions. Thank you very much!!
You make it seem so simple.
Thanks for all these informative videos
Really
I am just enjoying the learning of this complex circuit study
Thank you so much to make the study so much funny
Great, informative humorus and simple to understand.
Awesome demonstration. Helped me a lot thank you.
Awesome, I would love to see more in a series similar. You did a great job of explaining it.
Man, I like your style. Thanks.
just perfect.. thanks Collin
I't about time you gave us a new vid please dont have such a long wait !!!!!!! but thank's again Hip hip hooray Collin
You can magnetize your screw drivers to hold screws by doing the same method.
Correct
I'd want collin explaining more things to me, he's 49 types of awesome.
Very informative channel for an electronics newb such as myself... cheers!!
We are doing a project in Engineering design using coil sensor to build a system that can distinguish between metallic and glass ball.
thanks for the video
Beautiful absolutely beautiful !
a capacitor stores energy in its electric field. The field is created when opposite charges stored on a conductor are separated by an insulator like air. The charges then create a electric field which between them which "originates" from a positive charge and "ends" on a negative charge.
A capacitor is reluctant to change voltage, and stores the charge as a potential differential between insulated plates. An inductor is reluctant to change current, and stores it as a magnetic field.
I like your style, man!
I love this guy and of course the music which is playing in the beginning :D
I like this. Very relaxing style.
I 100% agree with Milo who commented on how some persons can teach but cannot explain it in a way that one learns from it, you do teach and explain it very well. I just finished building an electromagnet using a D battery and a screw wrapped by an insulated wire. One huge problem: as soon as I connect the negative wire the wire gets very hot and starts to smoke and I burn my fingers. Question: Is there a way around the heating and burning aspect to this project??. Thanks. AL.
difference in # of windings between primary and secondary coil, depending on whether secondary coil has more or less windings, voltage rises or drops
Thanks for helping me improve my knowlage base, but the you need more close ups and use of "the eye brow lift" to dramatize significant points. Keep up the good work. Oh and messy hair gives your a distinct edge.
Well done. I'm a Joseph Henry fan.
Quite intresting way of presentation...
Great videos, your calm approach to teach is super relaxing and enjoyable, and best of all, easy to understand.. Keep it up please
@ABCElevator I was taught in 1987 that when turned on in the first pico-second the current in the Capacitor is maximum and the voltage is zero because it is an effective short while in the first pico-second the current is almost zero and maximum voltage in the Inductor because of maximum 'rate of change' of current generates maximum 'rate of change' the the flux which induces maximum voltage.
@JagdtygerII the current doesnt get decreased in increasing voltage, the max current output stays the same at 200volt as it would have been at 1.5volt, so thinking he ment a battery, it wouldnt be "much".
I thought he was wearing giant DJ headphones the whole time, but it was his hair playing an optical illusion.
it depends if you consider the flow of current through the circuit or the source of current
Yes. I wish RUclips existed when I was in engineering school.
the electricity comes from the power plants at very hifgh voltage, and is then converted down to the voltage that is in our houses. The reason for it being high voltage is because the higher the voltage, the lower the power loss is.
i like how wearing 3d glasses actually makes the title/credits in this video look 3d.
This gentleman is really wonderful........!!!!!!!!
@alsports2000 No :D since an inductor is also a resistor, it heats up! more turns will reduce the heat though!
only works on hearing aid transfering the sound from the telicoil loop to the hearing aid telephone mode wireless way.
And inductor also behaves like a resistor... because of the resistance of the wire itself. There's always leakage and power loss, even though it's not too much. As said in the video, when you connect the coil to a DC power supply, it's reactance is 0, so the only remaining resistance is that of the wire, which is very small, thus a lot of current passes through it and heat is dissipated. P = Q/t
AAAHH, Perfect for my simple Project :D!
You're Amazing!
Nice, clear explanation! I definitely learned from this!
