It was a fantastic analogy. However, could you explain it in terms of vectors? I'm struggling to understand where the 'extra' or increase in voltage (thus force) is coming from.
but ,I mean in real life when you hit the brake you can't assume more speed , you just continue to carry the same "moto" you have, first that something stop the moto of the thing that carry you.. (third principle of dynamics) you are more faster then the car that is actual breaking but you are not faster than the initial speed of the car !! so how an inductor could boost voltage ?? what's another easy explenation?
Just an great down to earth instructor. Really helping this old dog understand, picking up my comprehension and trouble shooting , the electronics end of elevator controllers.
I've watched this with a huge smile on my face. Perfect explanation, but at the same time incredibly easy to understand. Big THANK YOU, Louis. I appreciate all of your videos.
Awesome explanations Louis! I know a decent amount of electronics from my university studies, but always find myself not knowing what things actually do, and what you are doing is what everyone needs, a basic 101 that tells people exactly what the basic functions of the components are in application, and sadly it is always the one thing you never see. Keep it up !!! ( And hello from Scotland :) )
very well said.. Actually be it an engineer or an amateur, we need to have a clear practical conception.. I liked this channel a lot and I've subscribed it.. I would like to stay connected.. all my best wishes with u.. Never stop this please
Your videos are both funny and informative. That keeps the viewer happy and they will not notice that they're learning new stuff until it's already too late!
lol someone had their coffee on this day of May 2015. Thanks for the videos, man. You have no idea how grateful I am. The inductor as brakes on a car making you jolt forward in your seatbelt got me the closest to understanding the increase in voltage out of anything else I've heard. I'll have to revisit this video again once I get some sleep. I've been up all night watching your videos, finally got around to finding your beginner playlist because I was being thoroughly entertained by your videos that were way over my head before I got here lol
+Louis Rossmann As a very enthusiastic hobbyist interested in electronics repair, I find your down to Earth examples and explanations very refreshing. I've spent many hours researching subjects, such as "The Transistor" only to find the purely scientific explanation. You certainly know what I mean; electrons, holes, and recombination. But, this explanation completely misses the mark when I am wanting to know about its interaction within the confines of a circuit. So, your channel is especially valuable to me. Thank You for passing on your knowledge in a clear and concise manner.
When I first started watching your videos years ago I was mostly here to learn about your PPBUS, milipauls of flux, and shitty apple flaws. Recently, however, I got more into working with circuits and micro controllers and went "hey, Louis Rossmann has a video on this shit right?" Now when I fuck up a circuit at least I know just how bad I fucked it up. Thank you for all your content, from your tutorials to your PPBUS, you've helped me in more ways than one!
Nice to bring an oscilloscope . Nice to see the video - helps understand things better & faster. Good stuff for beginner tortured by back emf, permeability, teslas, webers etc.
Louis you are the man! Thank you for making these capacitor and inductor videos. Ive always struggled wrapping my head around the two. Your explanations make it so much easier for me to wrap my head around. I look forward to more of your videos. Subbed
You had me at "fuck all that shit" lmao this is great. Your analogies are spot on. Torture of the molecules, and manipulation in a bad relationship. Simply brilliant and brilliantly simple.
I've learned more from your video here then I have in the last year Watching other videos! The key thing is I want to know what they do (electronic parts) & why we need them to do it!
that video was a watch more than once, make sure you get it video. i have unknowingly been waiting for this type of video. i like the teaching forget hz freqency henry just an explaination of whats going on and why. excellent video.
I learned electricity by thinking of it as water, or any fluid. I look at the positive as the faucet, or other water connection, and the neutral or ground as the drain. So if I ever am dying to figure out a circuit, I just look at the wires or traces and picture an actual flow of electrons.
Thanks again for the power point - and I am gonna get me a multimeter ASAP. As well as some schematics - perhaps for a Google Risio 4. Just in case I need to fix my device.
"I'm targeting the person who opens an electronics book and goes, 'oh my dear god' and puts it away for 5 years" Hello from a guy who picked up, "Practical Electronics for Inventors" after 3 years, and immediately put it down to come to TH-cam. This explains everything super well.
Poor electrons. I'm going to start an electron advocacy center. Sign my petition for electrons' rights. All kidding aside. Thank you for the video(s). Again and again.
I like to think of capacitors and inductors as being conservative: they resist change. The cap resists changes in voltage by swallowing or spitting out current in whatever direction will counteract the change. The inductor does the same, just with 'voltage' and 'current' reversed. Fun bonus: if you connect both together, you get a circuit of 2 conservatives who fight each other by changing what the other one reacts to change in... They will argue back and forth over it, until the resistance present in both of them has drained them of energy.
I'm sure the same can apply to components on a circuit board, but in automotive I get told I don't need a scope to diagnose. That statement is usually said by someone that doesn't know how to use a scope. There is a lot you can tell from, say, the waveform of a injector turning on and off. You just have to know what you are looking for. Or say, taking 2 traces, 1 for cam and 1 for crank. You can tell just from the 2 traces if the timing jumped on an engine. In about 10 minutes. Instead of at least an hour of tearing the front of the engine down to physically look at the timing marks. So yes, a scope is a great diagnostic tool if you know how to read it and use it
Think of an inductor as adding weight to the electrons. With a standard circuit, each electron is like a nippy little motorcycle. Easy to accelerate and easy to stop. With a high value inductor, each electron is now a heavily loaded bus. It takes more energy to accelerate (increase the current) but it is carrying more energy and if you run that bus into a wall (open circuit), the crash (voltage spike) is bigger compared to the low value inductor (motorcycle). In a water pipe module it is like putting a turbine connected to a heavy flywheel in the water pipe. In a hypothetical pure superconducting inductor, the turbine would be lossless, converting the energy in the water into the flywheel. If you closed a valve, the flywheel would be forcing the water hard against the closed valve via the turbine. This creates a massive pressure spike. If you want to know how a DC voltage booster works, research a ram pump and imagine the water is electrons. It lets a large and heavy volume of water water run up to speed and then stops it suddenly, which can create a big enough force to shove a smaller volume of water at high pressure up a pipe and raise it a large distance out of a river.
Your seatbelt analogy suggests that a current of electrons has momentum. Am not sure why they do, but it is like water hammering in plumbing: turn the flow off suddenly and you can burst a pipe. The normal lower voltage (pressure) of the water, when suddenly stopped, greatly increases at the cutoff valve. Thanks.
I am no physician, so take my words with a grain of salt (maybe two), but i think that the hammering effect of water upon an abrupt interruption of its flow is due to all the kinetic energy that made the water move until that moment suddenly being dumped into the system as the water no longer moves. This energy most likely gets transformed in mechanical energy exercised from the fluid against the valve and heat, which in turn determines an increase in pressure. Hope it helps (and also hope what I said is true, but I'm quite confident it is).
The effect of an inductor in a circuit is to oppose changes in current through it by developing a voltage across it proportional to the rate of change of the current. An ideal inductor would offer no resistance to a constant direct current; however, only superconducting inductors have truly zero electrical resistance.
I find the seatbelt analogy pretty misleading, it makes it sound like the higher voltage is generated when shorting to ground, when really the opposite is what's happening ... probably it's just me. nonetheless thanks for your videos, I find them really entertaining!
I'm concerned that there's only one other person aside from you pointing this out, and that everyone is accepting this video as correct. I don't know a lot about boost converters but I know enough to know that Louis's explanation is completely wrong. Even if it did work the way he described his own analogy is completely flawed "instead of you moving at your steady 20 miles an hour your moving for a split second at 40 or 50 or 60" - that's obviously not how physics works.
Man I feel so sorry for electrons after watching all your videos, good analogy though, never had someone explained electronics so easily to me
4 ปีที่แล้ว
Dude I wouldn't expect you while searching for this video. Thanks a lot for the video :) I believe you should also make pure educational videos nowadays. Maybe apple engineers can also learn a thing for the iPhone 12 :D
It's after the short to ground is suddenly removed that the voltage spike is created. Imagine all the electrons accelerating in the shorted loop and then when they are at speed you barricade their easy route and they go shooting towards the backlight circuit at high speed instead. Then the capacitors average out the voltage by storing and releasing charge. To lower a voltage you are simply using the inductor to smooth a high voltage pulse. If your car accelerator cable stuck so you could either floor it or have no power. No variable control. If you floored it all the time your car would go too fast so you would have to jab at it at just the right rate to keep the car going the speed you want.
14:56 this was the input pulses to the inductor right? and 15:46 this is the output from the inductor? If possible please show us how the output will look like without the capacitor. Thank u
The only thing I would change which is guess is a little pedantic of me is when you said you’re stopping in the car and you go for a split second at 40-50, it’s not true you’re still going at 20 mph like the car was, the only difference is it’s no longer moving relative to you, so the seat belt holds you back and at 20 mph. That’s a lot of momentum being stopped in a fraction of a second though so that’s why it’s such a large jerk ( or impulse ( change in momentum))
Just a remark.. instead of thinking it as manipulation in a bad relationship you could think of it as manipulating water :P like in case of the inductor .. you could imagine a big pipe of water flowing towards and smaller pipe of water (thickness or in other words how much quantity of water exists within the pipe is amperage and speed of water is voltage)
12:00 i don't get it, if you get the transistors to do the pulsing and singe you don't need a gain then why do you even need an inductor in this situation?
All right explanation but I feel like it would be better if you actually went into more detail like they do in school. You really need a mix of both to get what's going on. Instead of just saying an inductor passes low frequency ac.
Not enough teachers, or text book authors seperate the 'hardware' ,or mechanics of electrical devices from the software. You dont have to know how and why a component does what it does in order to fix a device. You can, however be sure that what whatever it does, the component/device you're working on is doing what it is supposed to be doing. Even if you dont know what that is.
olny a diehard cinic,(myself included)could look at electromagnetism in terms of toxic relationships with humans. Wierd? yes. but its perfectly true, just spoken in a different language
this explanation is wrong - boost happens when switch breaks path to ground since inductor resists change in current and way with low resistance doesn't exist anymore, current is going through larger resistance path, and according to Ohm's law V=IR - more R - more V
explanation on buck converter is also partially wrong - it's not only averaging - ironically, "averaging", i.e. integration is done by capacitor (frankly speaking it's one of possible interpretations) - and you are explaining inductor... there is much better explanation as loss-less voltage divider.

WOW this is so exciting Louis!! Been watching your videos for years, and just now got around to start this lessons, loving them man!
That analogy with the seatbelt really hit home for me. Many thanks!
I'm glad to hear it!
It was a fantastic analogy. However, could you explain it in terms of vectors? I'm struggling to understand where the 'extra' or increase in voltage (thus force) is coming from.
+BlinkY it has to do with electromagnetics. I dont know how this works exactly.
When the magnetic field collapses is where you get the voltage spike from
but ,I mean in real life when you hit the brake you can't assume more speed , you just continue to carry the same "moto" you have, first that something stop the moto of the thing that carry you.. (third principle of dynamics) you are more faster then the car that is actual breaking but you are not faster than the initial speed of the car !! so how an inductor could boost voltage ?? what's another easy explenation?

Changing the trigger level on the o-scope should hold that screen from flickering on the other side of the inductor and give you a clean wave to show.
Poor electrons we manipulate on a daily basis:) best explanation EVER...

all natural things gravitate toward entropy.
accelerate not gravitate ,.,.,.,what do u think

that reduction method uses alot less energy than a voltage divider it seems
