Electronic Basics #16: Resistors

[@Werede]

You are the best electronics youtuber ever. Love your videos

[@greatscottlab]

+Werede Thank you very much ;-)

[@Werede]

+GreatScott! You should make a Instagram account man

[@vgamesx1]

+Werede I can certainly second that, while there are some good youtubers out there, not many are as straight to the point and as simple to follow as GreatScott videos.

[@JaqiesGadgets]

+Werede Agreed! His personal style of building is so much like my own that he is the only one I support on patreon! However if Julian Ilett (check his channel out!) had patreon I would support him too.

[@vgamesx1]

JaqiesGadgets Not quite as entertaining as Julian but don't forget about bigclivedotcom he sometimes does some interesting tear downs.

[@tehEngineer3]

2:17 That Arduino sure is excited to see you.

[@lelandclayton5462]

About time a resistor video covers the wattage size of the resistor.

[@CSharpa]

I was searching for resistors on youtube.Then a notification came up.Guess what?You really read my mind .

[@greatscottlab]

+Sharpa Alex Good timing ;-)

[@JS7457]

+Sharpa Alex Damm ! I thought they was a fly on my screen.

[@leopoldojiao609]

Sharpa Alex it's KZbin who reads your mind

[@XerosXIII]

I need a resistor to limit the amount of info to my brain now

[@XerosXIII]

cant resist the temptation

[@rahimkvayath]

Married or not ?

[@vedurj9723]

How to calculate a MOSFET or bjt or igbt gate or base resistance..??

[@PixelOutlaw]

I was lucky enough to have a friend point out the need for resistor on the ground of a button or switch. Usually you just think of a switch as open or closed but you neglect thinking that that electricity needs to be grounded properly. Good point to cover it in a video.

[@umcuriosoeumaprotoboard6559]

best eletronics youtuber ever !! great video

[@leopoldojiao609]

Um curioso e uma protoboard true

[@camshotproductions1094]

Because of those burning demonstrations, I feel very, very small to myself that I am just scavenging electrical components even the tiniest components. I'm not saying it's bad but people says that "it just cost little" and sadly, it cost much for me, especially I'm not capable to work and get salary because of my age. No all out support and no access at new stuffs, only old things and reused "customized" crappy pcb. So basically THANK YOU GREAT SCOTT for all those knowledge, I still managed to survive this passion of mine and doesn't know when will it last.

[@wartoc3708]

Taking stuff apart is a good way to learn how things work and how circuits are designed in the real world rather than a basic tutorial or schematic that assume optimal conditions. Reverse engineering is invaluable. Plus your soldering skills get better.

[@fakiirification]

nothing wrong with salvaging. There are tons of useful things to pull off even modern PCBs. why pay for it if you can harvest it from something destined for the landfill? Ive even successfully repurposed SMT logic and opamp ICs and voltage regulators pulled off things. They are a pain to get off without destroying, but that experience makes me better at working with the tools of the trade. plus, its just fun to see something work with "scrap" parts, even if you have to add in a few new parts with it.

[@AlexandrePicotte1]

You are so helpfull! You vulgarize complicated stuff so well and we learn so much from your amazing project. Please dont stop what you are doing because a lot of future engineers are learning from you.

[@C.Paul09]

Hey Scott , i just started highschool in electronics and i love it to bits . I'm so intro your vids and learning new stuff from Electronic Basics , you're a great youtuber , thank you and keep up the good work buddy ! ;)

[@Lab0RatorXV3]

please, just continue making these educational videos , i really love them.

[@HeinzizBaKeD]

Your videos are the best! I bought myself an Arduino starter kit off Amazon. But I haven't yet started using it - I want to watch as many of your videos first so that I have a bit more understanding how everything works. Your videos are extremely helpful! Watching all the way from South Africa!

[@Jono6671]

Wow, these videos are amazing Great Scott! Please know that lots of us are really loving these :)

[@greatscottlab]

+Jono6671 Thanks mate ;-)

[@reff9203]

+GreatScott you're the best youtuber for electronics with dave greetings from Greece

[@leopoldojiao609]

True. He is the best electronic youtuber

[@MarkJay]

you make great videos. I've learned a lot about electronics and even feeling inspired to tinker with my arduino. keep making videos please!

[@anthonyvolkman2338]

Your videos are great! I enjoy watching tour vids even when I've known the information for years already and use it all the time on a daily basis, but every now and then you show something that I didn't notice before it at least it brings it back to memory to assist in current projects. Thanks for your excellent tutorials and informative videos. Volkman Audio Repair

[@nacejehart6969]

The best electronics youtuber

[@mikael5914]

Hi Scott. I love your channel cause it's stuffed with information. The only problem is that you really shouldn't call this "basics" as I'm trying to learn electronics and find that after every 10 to 20 seconds of video, I google something and spend 10 to 20 minutes trying to grasp some concepts. So what I wanna say is that these "basics video's" are really more of a "table of contents".

[@k1radev]

Best electrical engineering videos on youtube !!

[@Vincintosh]

I always wondered what the music is. I don't mean "killing time" but the other one that plays right after the intro and has been played for years now in any GreatScott video... For me it has become the GreatScott's song

[@Darkbart22]

Schöne Videos, einfach aber gut. Schau ich immer wieder gern. Mach weiter so!

[@Hugatry]

Infromative video, with multiple good examples. Can definately recommend this video for beginners!

[@IIGrayfoxII]

I hate those small carbon resistors with blue bodies, makes looking at the bands hard

[@muhammadaarizmarzuq295]

Lol, i rarely use them, i really enjoy the ones with four pins, they're easy to read.

[@EnhancedNightmare]

I love the series man but the difficulty is all over the place. This should be one of the first lessons. We seen some order here :D

[@richardbrown9522]

Awesome videos! Thanks

[@NicholasAarons]

Awesome Video Dude. Keep up the great work. Nick.

[@GenosetScentia]

Loving this channel

[@muflah]

That last led burn was like electroboom. 😁

[@jpiko]

Q: ESR and other handy stuff meter at 5:38 ... did you make it yourself? Are there any schematics? What keywords do I search for?

[@greatscottlab]

+Jernej Piko Search for "Transistor Tester" on Ebay or Amazon

[@user-28qhfk65]

Wow this video explains to me better than my highschool physics textbook, I can't believe that 2015 is 8 years ago

[@GustavSolin]

Great and informative video as always! Would be nice to see a video about "how to build a potentiometer controlling a bigger current and voltage circuit by changing the voltage"

[@bestestinventions7032]

i love your handwriting

[@guettadavid188]

You should make more 3d printig videos.The technology is very interesting and you are such a good explainer.

[@nattybumpo2012]

Hello, just stumbled upon your site. It seems that you have done 100% of the work for all your various projects/labs. Have you considered putting together packages of the various components (as they relate to the projects), and selling them? Since the demise (for the most part) of Radio Shack, it's not as simple as it used to be to have electronic components within driving distance, so to have all the necessary items for your projects would be (in my opinion) a value added nicety. thanks again

[@WobblycogsUk]

Great video, one of your best.

[@unclefreddy2009]

You should develop a basic electronics course, I would pay to watch it. Great stuff...very easy to understand without going too slowly

[@imho2278]

he has. watch his vids.

[@BritishKnightUC]

how do you make one of those resistor lost tools where it tels you the lost between volts at 5:32

[@Leandur]

On a sunday, I always get bored. However, when I get notified a video from GreatScott! has been uploaded, it makes my day :-) Keep up the good work! Btw; How did you learn all of this?! ;-)

[@greatscottlab]

+AddictionGaming Work and university.

[@Leandur]

+GreatScott! Nice! Keep up the amazing work!

[@xsoul6838]

You are awesome you talking all about pro level and scientific explaining... you are also too hard for beginners D:

[@isaiahnelson3643]

+GreatScott! Is the effect seen on the serial monitor at 3:09 before the pull up resistor was added some kind of "parasitic" effect?

[@greatscottlab]

+Isaiah Nelson You could call it that. The pin does not have a defined state and is "floating".

[@Retroweld]

Awesome!

[@jasonperry6046]

I am starting to get into electronics thanks you yourself and a number of other KZbin authors. I was wondering if you had a list for components that you recommend to have on hand for beginners so I am not going out and getting single components for each new project.

[@EstBest69]

You should do a short Electronic Basics video on potentiometers.

[@arroncervantes4248]

keep it up man. I am learning a lot thanks.

[@iwanname]

very great explanation !

[@joeyboekel7304]

you are the best man

[@MeisterVasqus]

Firstly its my first comment on one of your videos. I love all of them. Mach bitte weiter so :D ! I have a suggestion for a future project. How about building one of those resistor/Cap testers you used at 5:30 (i dont know how they are called) would be awsome! Thx and i will see you next Time

[@greatscottlab]

+MeisterVasqus Search for "Transistor Tester". They are quite cheap.

[@danymaster1997]

you do a very good job in your videos, I want to know what program do you use to make circuits in computer?

[@greatscottlab]

Eagle

[@asherejoseph1652]

I've been studying circuits and discovered a fantastic resource at Gregs Electro Blog (check it out on google)

[@emertes17]

Keep making these videos!!!

[@JaqiesGadgets]

+emertes17 give him $1 per month through patreon and he will!

[@kernelx4868]

What a coincidence. I uploaded a video about resistors just an hour after yours.

[@kernelx4868]

Check out my video as well if you like.

[@greatscottlab]

+The Nerd From Another World Your video is quite nice, but a bit short.

[@kernelx4868]

+GreatScott! I know, I will try to make a better one next time.

[@naderhumood]

Vedio is super i like it, but the explanation is a bet fast any how thank you Sir I like your approach. Your great.👍

[@CSO3DOnline]

did you just completely blow up that LED? wow never seen that coming

[@greatscottlab]

+~☆ XzCraftP ☺♂ Neither did I back then.

[@KuroYoukai]

+~☆ XzCraftP ☺♂ I wouldn't call that blowing up a LED. I once saw what happens when you apply 400VAC to one. There wasn't anything left of it.

[@JaqiesGadgets]

+KuroYoukai if you like that kind of thing watch photonicinduction 's videos! he's frikkin INSANE!

[@mort7987]

+GreatScott! i onece blew one up. like LEGIT BLOWN UP. The parts were all around the room afterwards :D

[@bhanuchandar4820]

d

[@imho2278]

that's a year's worth of uni in one hit. Cool!

[@isbestlizard]

wow transitor testers are useful! i'm going to get one from banggood right now!!

[@TechBuild]

Please make a tutorial on 16X2 LCD display.

[@3ds12Game]

HELP! i just don't get it, i go arround the whole web and even GreatBestScott! doesn't ring a bell in me about how to use them. What do i do when i have (for example) a 9v power source and i want to power a 3v led. What do i use and how do i calculate this also for other variables. What, when, how, why???? I'm so confused about this.

[@JohnnyTsc]

2:26 Why he said one can't use that as a stable power source?

[@nistax2880]

coz if u Draw current from it the voltage will ***g o d o w n***

[@konradpeter9547]

Whats the name of the device at 5:27? My multimeter cant do capacity or that small resistance mesurements, so it would be nice to have one...

[@greatscottlab]

+Konrad Peter A Transistor Tester.

[@konradpeter9547]

+GreatScott! Thanks!

[@someguy3032]

Great video!

[@Sytrag]

Anyone can pls. tell me what's the name of gadget he used at 5:27 to measure low value resistance and where to get it? Thanks in advance.

[@greatscottlab]

+cloudbreaker ninety Transistor Tester. Search for it on Ebay.

[@sapperjohn256]

at 3:35 shouldnt you have had the meter in series with the circuit when measuring current? Thanks, love your videos

[@nistax2880]

he does tho

[@raym9691]

what is your recommendation for storage and or sorting of resistors? I have been trying to figure out a easy yet efficient way to sort and store them. Keep up the great videos!

[@austinderp2475]

1:44 keeps triggering my Google home 😂

[@kadsmoto139]

hi i want to ask if how many ohms/watts of resistor should i use to light up a 40 smd 0603 with 3.2v each and 20ma each using a motorcycle battery 12v and when charging up to 14v and what kund od resistor should i use. thank you

[@DennisMathisen]

What is the thing you used near the end of the video, to measure resistanse? Where can i buy it?

[@julieedem9018]

Nice videos How did you get your drawers of electrical components

[@iProgramInCpp]

Do 1 Kohm resistors work for pull-down?

[@1love1heart87]

Thank you this helped me right out .

[@ScienceMarcYT]

What's the device at 5:28?

[@matplaysmc9313]

well im learning things thanks scott

[@MkmeOrg]

Very well done! Cheers

[@danfishermen5362]

Hi MKme lab

+GreatScott! do u install flight radar ads-b??

[@yuby985]

Verry nice, you are pro man! See you nex time! :)

[@sized4spills]

Great video!!!

[@ziuretity]

Who was wondering about studies, at this point (if u watched all of his basic videos before this one), that is pretty much 1 year of electric engineering studies in university. So now you know :)

[@woutvdr]

nice video!

[@davidwithawiredprofile]

what type of resistor do i need for a input voltage of 7.4v and a output of 4.5v

[@AdhipBhargava]

you have the best ideas for editing electronics and making those.....so why dont u start manifacturing them.!! +greatscott

[@micnor14]

What is that electronic tool I see some youtubers like you using @5:26? I want one!

[@MrJason005]

+Mic Nor An ohm meter?

[@reverz3]

+Mic Nor www.ebay.com/bhp/transistor-tester

[@micnor14]

+MrJason005 I meant like one with several types of inputs that can check many things at once. On paper calling it a multimeter would make sense but this thing beats my old multimeter.

[@driveitbreakitfixit7496]

what was that thing called that you used in the end of the video to find the the value of copper wire and resistors?

[@andruloni]

Look for something along the lines of "electronic components tester"

[@amanb5598]

I need to drop 12v dc input Amps from 100 amps to 2 Amps what should I use .

[@jdaniels8809]

thank you for your knowledge

[@tayebanwari]

I would like to use 12 V and 12 Ah battery directly as a power supply to a DSL wifi router, once i used and it burned the device, i decided to use resistor, but still i'm not sure how to use the resistor , can you please guide me?

[@IndianHackingguy]

how we can know the value of a variable resistor

[@diamondsprince]

use a multi meter to check it if there isn't a label on it telling you the maximum resistance.

[@IndianHackingguy]

diamondsprince thank you

[@PsSarvna]

indian hacking guy ,,,there is a colour code in the resistor to calculate the value of resistor,,,

[@IndianHackingguy]

Ps Sarvna I am talking about variable resistance

[@රෙසාද්_ඉන්දිප_04]

hey great Scott what is the circuit you build first with a LED and resistor. plzz tell if anyone tell me

[@slawor4]

a lamp?

[@OliverMappin]

I love your vids there the best

[@monellotremendo]

+GreatScott Can you make an inverter?

[@Cristi0986]

If i had 100miroampermeter and i whant to mesure 100kv what rezistor (100A 100mv shunt is god?)should i use?

[@MultiDrago22]

Hey, ich habe eine Frage bezüglich einer Schaltung. Ich möchte einen 12V LED Streifen über Batterien oder über ein Netzteil Powern. Doch wie muss ich das verkabel, dass jeweils nur eine von den beiden Stromquellen meine LED's zum leuchten bringen? Danke im Voraus! MfG Alex

[@PoanteleTARI]

Can you show how i can convert 12 v (for example a car battery) to 220 v?Thanks

[@Binda5000]

Whats that tester ant 5:29?

[@greatscottlab]

+Chrisi Bi A Transistor Tester.

[@harukoyama9515]

Like all ur video. Very educational. Never took any electronic class before. Trying to modify existing world. There is Metal Wood Fire Earth Water... Wind Gravity Electricity Thermal and many other known and unknown force in our known world. MicroWave Transformer... I was wonder if exposed wire portion end is also capsulate with same metal . will that make transformer more efficient? Or just a waste of material? What is the reason for EI shape? Why not small O inside big O shape? Or any other shape? Is EI plate just metal or some kind Simi conductor, what can I use to experiment with different shape?

[@tpespos]

I still don’t really understand pull up and pull down, I understand then for applications because I use them but I don’t really get what they are doing. Looking at the schematic to my untrained eye I don’t see the what the resistor is doing

[@harishrajamani4922]

Hi can u guide me which type of resistor? are good for a 5w uv led wit 3.4-3.9volt n 1.4amps n im going to used this 3 led in series wit 12v 5Apower supply.

[@nistax2880]

just , calculate it ?

[@phagusandjiet4872]

you're the best !

[@Gurke01]

Hey Scott, im going to build a small electronic area. I got pretty everthing covered, execpt the storage solution for resistors, Leds etc. Do you have a tip or Purchase recommendation? Due the fact that i live in Germany, Its ok if you send me and link to an german shop site or sth. Btw Great videos!

[@vedurj9723]

How to measure a MOSFET ,, BJT or IGBT ..gate or base resistance ??

[@Axel-ro7dn]

Isn't an LED a very special case ? It's a current driven semiconductor, the resistor provides that current (if there is no resistor, the wire provides that current, therefor very prone to over-current if voltage is too high)

[@gabejanssen4826]

I'm new to electronics but i am wondering what would happen if you put a resistor in parallel with a DC motor. I know it would limit power, but I am wondering in which aspect

[@nistax2880]

wdym witch aspects

[@mjafs9671]

you rock bro
