MAKE presents: The Resistor

[Iceni77]

These videos make me want to learn more. My brother is an EE and he does have a talent for teaching, but you summed up in 5 mins what would have taken him a week. Thanks for sharing the knowledge. I'll be referring to this video often.

[sodomyandlust91]

interesting, so does it matter how dark you shade in the resistor on the paper???

[SmallElectronicsMan]

You rock

[Moongazerr]

Bad Boys Rape Our Young Girls But Violeta Gave Willingly

for resistor color coding.

[Evanator22742]

@Moongazerr

Ha, my electronics teacher taught us that.

[brenan6]

You know, I have a receding hairline, and this is the first guy that pops into my head when im standing there at the bathroom mirror thinking "ITS ALL OVER" this guy looks fucking awesome. This guy knows how to pull off the receding hairline. He gives me hope. :')

[jgrecoarroyo]

Really nice experiment, I will try out different figures to see how it goes :)

[Deusex63]

WTF......... !!! 8-O

[getreal1776]

Before I watch your videos on you tube I didn’t know a thing about basic electronic component parts. But thanks to you now I do. Your videos are the best. Thank You. PS your videos are not bullshit! Some people are butthead who needs to grow up.

[ipaqmaster]

my resistor doesnt use a resistor.. HA

[Mbilla1]

R u faking Crazy in mind or what? What the hell are you doing? Bulshit Video about Resistors. Asshole

[mRwhite298]

Hello  how many Oms is need that 12 volts be 9 volts

[guinguinnaman]

@mRwhite298 depends of the cargo

[kindpotato]

does any body think how left out amperes must feel. they are like the only measurment ( when talking about electronics) that isnt named after some famous guy

ohms=ohm guy

volts= alexandro volta ( or something)

farads=michael farad

coloumbs= columb guy

amperes= nobody

[xplinux22]

@kindpotato Amps were named after a French engineer called Ampere. But nobody seems to care about him much... poor guy...

[EndlessEndorphins]

OMG you explain everything so well!!!!

I learned so much more here in 5 minutes than I did on Wikipedia for a 30 minutes. Thank You so much man!!!

[Tranqspogi]

cool!

[MrFunyman1234]

O_O I PUT MINE ON RLLY HIGH AND ONE LITTLE DOT GAVE ME 1405.40 OHMS O_O_O_O_O at its makin alot of static

[y2jshawnR]

cool ya

[vanjastanic]

wow, thanks for the idea of the paper resistor! you're great!

[vanjastanic]

I love the osciloscope behind you :D

[perkerfrans]

a shame with the music on when you speak. Hard to hear you.

[Nadrealis]

How the teacher taught us our color markers? Bad Boys Rape Our Young Girls But Violet Gives Willingly I shit you not. Do you know how messed up it is that I have to repeat that to myself to remember the color markers? :(

[YellowPikmin476]

@Nadrealis Baby Boys Really Owe You Great Bucks, Paul George Williams.

[Jhfgsjdcd]

Why isnt he making anymore

[left4james]

DON'T go to school you learn more on YOUTUBE no joke either I was thick once now im a genius

[Cammofluage]

damn they even making computer components seem racist

[TheHassanhass]

I am student of EIE(electronic and instrumentation engg.), its my first time to get some thing practical. Its good way of teaching.

[JotaLegendOfficial]

Around the world, Around the World, around the world

[Zaharkl]

i bled out like 10 led's becuase i didnt know how to use resistors, but after watching this video i see how they work and how to use thank you!

[Themanwhocanpiss]

Nice tie

[SebastianBoldt]

Its like Germans invent all the good stuff. :)

[stealth7769]

@SebastianBoldt

bmw's =]

[KROUTCHY]

we meet again... mr anderson

[bohdan1997]

How do we know how many Ohm's is needed to resist a certain amount of voltage or ampage.

[turf7227]

@bohdan1997 Ohm's Law: V=IR

V-Voltage

I-Current

R-Resistance(in ohms)

[JiraiyaZantIssun]

Someone please help I Have a jumbo LED and a 9 volt the LED can only take 3.4 volts what resistor do I need?

[bjarni1995]

@JiraiyaZantIssun Use Ohms law, Most LED's are designed to work at 20mA, since you have a Jumbo one i would say it needs 30mA. Now we take these values and put them in Ohm's law, 9v/0.03A=300, so you would use a 300 Ω Resistor.

Your welcome :)

[Bracerjack]

The reason I like ALL MAKE electronic videos is because it shows us that we can make our own capacitors, LEDs, resistors....basically telling us that they are everyday stuff and within experimentation and understanding, that our technology is not made by some space alien and all that crap.

[tim78704]

That homemade resistor out of pencil lead has to be one of the coolest things I've ever seen in my life :D

[frank0nh]

About to learn about resistor because I know 0% about it

[jtgober87]

i have read that using a resistor as a dimmer wastes energy via heat given off. is this true?

[ricardo161584]

hey i need your help

i have a 6 volt battery

with 6 leds that are 3.3v ...25ma

idk what resistors to use

[dwv91]

@ricardo161584 If they're in serie you will need a better power supply than 6V

In this calculation i used 24V:

6 leds * 3,3V = 19,8V

(24V - 19,8V) / 0,025A = 168 Ohms Resistance

If they're in parallel you can use 6V:

(6V - 3,3V) / 0,025A = 108 Ohms / 6 leds = 18 Ohms Resistance

Thank you :D i learned so much

[MiniGeek31337]

That guy is so charismatic

[MrRyanstutorials]

This is like super duper warp 9 Mach 10 accelerated math! And way more interesting..

[midoladido]

That's seriously helpful, thanks for your effort. I like the real example to illustrate the benefit of an electronic component. Keep the good work up. The best thing in the world to share the knowledge for free :).

[JJengineering]

thanks for watching?

well THANKS for loading this up man

10/5

[visualeffectschannel]

THIS is 5 minutes...at school we spent 10 total hours about it...the school system is WRONG!

[Digitalman271]

@visualeffectschannel They should give awards to things like that on how long and complicated the school system can make things seem.

[alternativeangle]

@visualeffectschannel check out the school sucks podcast ;)



[hitachi088]

@visualeffectschannel my god they are so retarded, you must be in canada! hahaha.

[visualeffectschannel]

@hitachi088 well they're not retarded, but they explain things like I'm a 5 year old, and they tell so much useless stuff...I'd be better if I'll just be my own teacher :o

[swrbigtex]

does anyone else notice that he looks like agent smith from the matrix?

[SaltedSlugs]

@swrbigtex No.

[UroborosComplex]

@swrbigtex lol yes he does, but he's really cool, I enjoy his videos very much.

[00sven00sven00]

He looks like Greame from the Goodies!

[brandon14872]

makezine has iploaded 555 videos , 555 like a 555 timer chip

[ROpaulinu]

in school i learn I=U/R

[WilltechOnline]

@ROpaulinu There are different symbols used to represent V. It is also sometimes referenced as E.

[WilltechOnline]

@ROpaulinu There are different symbols used to represent Voltage. It can also be represented as an E for Electromotive Force of EMF.

[97273998]

@ROpaulinu out of school i lernt e=mc2 and im not in highschool XD

[UroborosComplex]

@97273998 now go learn on string theory / michio kaku or brian greene

[kikonin0]

lol moves his eyebrows alot!

[SwisssBolla]

@kikonin0 Try to look at people reading the news in TV... they do the same.

[saggster20]

Learned more than i ever do in school.

thank you.

[TheVintagePiano]

Thank you.

[MJLaukala]

For all you guys having trouble remembering the table or are still looking of a "cheat sheet", I wrote a free program to help you out. Here is the link to the quick tutorial on how to use the program. The download link is in the description. youtube.com/watch?v=nolRA9ZmK-­U

[Undeworld667]

Lol this guy is a cool character

[ayinozendy]

OMG, if only I knew about this in elementary...

[Pyrotach]

how do you read the resistor? i found an old resistor and it has one red stripe (2) and a brown stripe (1). does that read 12 or 21? plz help!!

[snoobeagle]

@Pyrotach Hold the resistor so that the stripe closest to an end of the resistor is on your left. This represents the highest digit. ---[RB ]------ if this diagram is a red and brown stripe, this would be 21. There's probably going to be a metallic color as the last band, showing the tolerance (accuracy) of the listed value.

[Tomi852]

@Pyrotach There should be more bands on your resistor (at least 4), without those I can't tell the value. Type 'Resistor bands' to google pictures and the second picture should help a lot.

[Tomi852]

@Pyrotach There should be more bands on your resistor (at least 4), without those I can't tell the value. Type 'Resistor bands' to google pictures and the second picture should help a lot. And read from the thin end to the wide

[D3athM3at]

its not I=V/R but I=U/R ..

[uut0]

@D3athM3at in america it's V/R the rest of the world U/R. and if you would write it with my handwriting it looks the same lol

[coolerwesbox]

what i like to do is stick low ohm ones in outlets and they smoke like hell

[stormtrooperandfett]

all he needs to say is "Mr. Anderson" X)

[stormtrooperandfett]

thats insane. . .

for some reason, he reminds me of the agents in The Matrix ahaa

if you know what ii mean =)

[UnchainedMinds]

man that homade resistor is BADASS! at first i thought you were shitting me, but that is cool.

[branda12on]

love ur vids more of collins lab

[zelenbic]

023 german flag xD

[johnhodgson90]

is that how knobs work

[ysflightman]

@johnhodgson90 A knob controlling volume or something similar is a variable resistor, so yes.

[mapukmapuk]

make makezin lol hahaa

[Ciaran55]

what synthesizer is that?

[TicTicToc]

@Ciaran55, it is a Sequential Circuits Prophet 600.

[justmarinus]

This is really cool!!

[123456cephiro]

Resistors OWNS!!!

[pikachuthesquirtle]

using equipment that he constructed himself. lol

[SAS9002]

stue

[raz0racanine]

bald!!!! bald!!!! bald!!!! MY EYES!!!!!

[SirArghPirate]

Some LED's come with the description 2V, doesn't that mean that a 9V battery will burn it out, or doesn't it matter as long as the resistor connected in series with the LED limits the current to let's say 30mA?

[TenFoldDamage]

@SirArghPirate if an LED is rated at 2V, it can only take 2 volts or it will burn out, As long as a resistor is used in series to take the other 7V load, you should be safe.

[lego3525]

what about gold and silver

[weesenz]

@lego3525 it is onli used for multiplier and tolerance..

[92blink182]

Nice video

[ciprianwiner]

awesome thanks alot

[IRONMAIDENFAN2006]

resister is futile

[dycarbon1]

Someone plz respond.

I thought LEDs do not work with dimmers? What is going on?

[TheGuyInUrCloset]

@dycarbon1 They do but they are a lot more sensitive, because Leds only work in a range of about 3-4 volts, (may be slightly higher or lower) vs something such as a traditional incandecant light bulb, which operates between about 1 v, up until alot of the times 120 or 240 v. So most dimmers are programmed to work between 1-120 and the LEDs will only fade out when it is between the 3-4 v zone. That is why they make special dimmers for LEDs that operate between 3-4 v.

[ElectroCompuGeek]

I like resistors. Electrical resistance is the reason why we have stoves, ovens and heating fans. High voltages (in relation to earth) force current to travel across highly resistive coils convecting heat to glass or metal containers thereby baking or cooking food or those resistive coils convect heat to the passing air flowing from the fan to warm me on a cold night.

[j5themrbravo]

No offense, but you look weird!!!!!!!!!!

[cinderblast]

he feels like a modern bill nye

[Jallandhara]

@cinderblast It's all about Beakman's World, my man.

[JUMBOpin]

this man is the shit...very tv friendly...but he still has a face for radio..bwahahahah

[ndawsome]

this guy freaks the crap out of me

[Jallandhara]

@ndawsome Something about knowledge freaks you out, or are you making a baseless statement because he doesn't look like you.

He harmless and smart enough to not judge people on how they look.

[ndawsome]

@Jallandhara fuck you

[Jallandhara]

@ndawsome I'll take that as a yes. I feel sorry for you, kiddo.

[VideyoJunkei]

That pencil resistor will get hot with enough current!

[RokuUnknown]

thanks!

[sdsurferinvestor]

The techie music that goes along with dialogue in your videos is brilliant. Thankyou for educating and entertaining simultaneously. Are you the founder of Make Magazine?

[pimbadoti]

you are very good man!!!!!!!!!!!

[animorphs123]

"and how does it do that"

my answer: "Magic"

[eshneto]

As I see, Ohms law is actually the definition of resistence. Am I wrong?

[chapin14maya]

doodd your progr is real cooooool thank you

[xvirg]

I resisted the advances of a beautiful woman once... for a while, anyway. My resistance broke down, and boy, did the current start flowing then.

[fireitup9]

this guy is a jagoff

[wodanamor]

But he's definitely smarter than you.

[matthehat]

What's the synthesiser at the beginning?

[iExD]

interesting... =D

[skmax95]

dude 1/2M ohm is A fucking lot for that thing

[driv3ver]

AVEsome and working with different color crayons?

[fireitup9]

whos this cocksucker

[ReaverRism]

3:31: i can invent my own resistor with this... :D

[samanthms123]

@ReaverRism lol sorry to disappoint , but the Resistor has already been "invented" :P

[pyronathanpyro]

i hooked this up to a motor instead of a led and added a servo to move the clip and whala a speed controller

[roxes787b]

what does a resistor with 0,25w and 0,1% what does the procent mean

[lasaldude]

@roxes787b A Resistor is measured in ohms not watts. Watts Is Measured for power dissipated. I^2*R I Think. Now The Percentage Is The Range(Negative Or Positive That The Resistor can operate) so a 1000 ohm resistor with 10 % can function between 1100 and 900 ohms. Because 10 % Of 1000 Is One Hundred. So Add Or Subtract A Hundred From It..

[icyfyer]

@lasaldude Resistors are also measured in watts. The wattage marks indicate how much power a resistor can handle. You wouldn't want to use a 1/4 watt resistor in a CRT deflection circuit for example because it would burn out.

[lasaldude]

@icyfyer I Understand what you"re trying to say about a resistor measured in Watts. in DC electronics that is the power dissipated, when current and/or voltage is applied to the said resistor. i understand its Watt rating when we have amps or volts, but a resistor is measured in ohms. It's The (Ohm's) In Ohm's Law R=V/I. Watts Is P=I^2*R Or P=V^2/R Or P=I*V. Not gonna preach because you already probably know these equations.

[lasaldude]

You cannot have a resistor in hand and measure its Watts, but you can measure its resistance with an ohm meter or multimeter or bench meter while its not hooked up to a circuit. You have to add voltage to the resistor to calculated it power in Watts.

[Kl4pp5tuhl]

No one ever told me how this stuff is either conducting or non-conducting, can anyone help?

[criticalzen]

Resistance is futile!

[Kankki1]

@criticalzen If less than 1 ohms!

[wecantsee]

@criticalzen what?

[pianomaple]

THANK YOU I don't want to buy or hunt down a real one so this on is perfect to use.

[T5226]

Why do the" white "LEDs flash different colors in the toy I bought in the Dollar Store ? Three LEDs in a row two button batteries , the 3 LEDs one in a holder all by it self. Yes! there's a mysterious brown lump on the bottom side of the circuit board.

[MuF123]

voltage = V? :)) since when?

[Kallenator1988]

Since I started education with electronics after primary school its always been U. However now at university we have to use V.

(In equations when voltage is present as a non numeric value =)

[MuF123]

@Kallenator1988

well at my university they teach us "U" however it isn't exactly top class school :D mmm wikipedia says "V" too... weird :D

[tehtud2008]

yeah, I also think it is U, but anyway, cool video.:D

[Ba3dadBoy]

Which country are you talking about where you use U instead of V? I think U is for RMS voltage and V is for instantaneous, or maybe the other way around.

[PivotLazerKnight]

since people started spelling it right.

[kuru2k9]

since 2002 I think, if you look at some computer components, hten you will some some of their values :).

[soapandwafflesrule]

thank you

alot

ur not the only one my man.... i m resistors fan too

[armouredhen30]

Tacoman8200;

The ground us like a third polarity that some circuits need I won't get technichal, but that is basically it

Google it or somthing

[danyellhyt]

Hey man!! Do you know how to make warm gloves ??? Please put a video on youtub. 10x

[karma6413]

There's really no difference with a high-strength resistor resisting something small like an LED, right?

[LedusZeppelinus]

just attach a 330 ohm resistor to the non-battery side of the LED and use that resistor as your probe. that way you won't have to worry about letting the smoke out of the LED when you connect the two probes on the pencil ash.

[20bogart]

hi sir can i know all the names and and pictures of alll the variable resistor tnx ....

[cobrachoppergirl]

this is intresting, because theoretically, with a couple of pencils and glue on components, you could draw a functional electrical circuit on a piece of paper. i assume if you can make resistors, you could make caps as well, by drawing surface areas on both sides of the paper and using the paper as the dielectric.

[20bogart]

hey i want to make an home laser security but 1 of my materials is a variable resistor what is it what is the use of it?///

[radiumsoup]

A variable resistor is made of organic conductors and ohmatic voltaics. You need a stranded current gate and some insulated ocillating filaments (I use at least 3 for safety) in order to prevent blowback. Take care that you limit the voltage to as close to 1/16th of the value of the length of coil for the best efficiency. Don't forget to ground the anode (I learned that the hard way!) and a farad-polarized gap meter is good for watching the non-linear signal decay, if you want to get real fancy.

[tacoman8200]

what is the point of ground wires on electric stuff

[cjmitz]

so that it flows back

[HeartWood154]

How do I know how much the voltage will be resisted with a resistor

[geekionizado]

Does the resistors low the voltage?

[lasergeak]

no .

[kecapo]

thank yor for video
