- เผยแพร่เมื่อ 1 มิ.ย. 2024
- LER #179 This is the 1st video in a new series looking at common components and circuits, from the perspective of a repair hobbyist / technician.
All you need to know about RESISTORS to fix stuff.
In each short(ish) video I hope to teach you all you need to know about the most common way in which components and circuits fail, and how to test and diagnose these faults. I'll try to keep each video to around 30 mins or less. Of course I will still be making the regular repair videos this channel is getting well known for.

I asked ChatGPT and it gave me something similar to this so I changed a word or two:
Beautiful Birds Return Observing Your Garden Bringing Vibrant Green Wonders
makes perfect sense cause birds could look for bugs in a garden and they bring greenery (seeds) in their droppings.
awesome videos btw! watching them to learn how to repair a broken fan on a Mosquito trap, love the explanations on how the components can be used and how to troubleshoot them!
I like it, although having the Green refer to Grey is a bit weird. Vibrant Grey Wonders makes it nice and tidy
another great one i found:
Blazing Bonfires Radiate Orange-Yellow Glow, Blazing(Burning?) Vividly, Generating Warmth
(apparently a chatgpt link gets marked as spam so i wont post it this time)
I was in school for electronics in the 80s in the US and our mnemonic was Bad Boys R*** Our Young Girls But Violet Gives Willingly
Really great video thanks! As a beginner, I particularly like the tips on the implications if a resister reads more or less than it's markings, probably obvious to many, but not always when you're starting out. I also like the way the videos often include occasional mistakes, rather than perfectly edited videos - good to be human and people often make similar mistakes. Great work! Look forward to the next one. Thanks for your help!
Just what I was looking for. Brilliant lesson! Thank you kind Sir!
You're very welcome!
Thank you for giving your time up to make these awesome videos👍
Thanks buddy!!! I Brought to life my 1965 car radio and its vintage reverberator in the “boot”. That made me feel really good!
Thank you so much for these videos! I start a job as an electrical technician tomorrow and will be studying these videos to help.
I was taught in the 80s to use, Bad Beer Rots Our Young Guts But Vodka Goes Well.
It seems there were some variations on that one, I never heard that mnemonic before. 🙂
We had as I mentioned Bill Blogs Raped Our Young Gladys Behind Violet's Garden Wall, and Black B**tards Rape Our Young Girls But Vicars Go Without (which was the more commonly know one)
I didn't use that one in the video as it could be offensive to Vicars 🤣
I like the first version because it contains the actual 8th coloured band 'Violet' and I liked the other one because it starts with the actual 1st coloured band 'Black' - where as your version contains none of the actual colours.
I wouldn't be surprised if others here knew different versions. They obviously worked as I remember them just as well 40 years later.
It seems 'Young' is a constant in all the Resistor Colour Code Mnemonics
Probably a bit more politically correct these days
Excellent video as always, very intresting series! Keep up the good work!
Thank you very much!
Excellent video. I look forward to more videos in this series! 👍
Glad to hear it!
Great refreshing video! And thanx for all the tips, they come with experience, that I don't have enough.
Simple and informative, thanks for sharing your knowledge Richard, I look forward to the next one :)
Thanks for watching!
Wow! Very very informative. Learning a ton of stuff there. Thanks for the lesson 😀
I am watching the repair series yet again, and hats down to you for an insane good lecture on electronics repair and understanding the main components!
I work as a electronic service and production engineer, and this is a nice refresher when you have spent to many hours soldering and mounting the same stuff for a long time, without thknking about what everything does and how it all works together!
Your a great teacher. Good stuff. Thanks
Great video. Thank you for the information. Excellent Job.
Great tutorial very informative looking forward to the next one 👍
Thanks 👍
many thanks for the Resistor video. I love the little extra bits of knowledge to tag onto the end of the main points, these are so difficult to pick up from formal text etc,
Know About RESISTORS To Fix Stuff, very good.We are factory but we can't use video explan it so good.
Starting your video course now. Thanks again
Very valuable and informative lesson, thanks for sharing.
My pleasure!
you are really great thanks for giving out this valuable information master 🙏🙏🙏
Thanks for the knowledge.
Brilliant Knowledge, Thank you for sharing.
My pleasure!
Excellent video…please keep up the great work - Darrell 🇨🇦
Thanks, will do!
Tu very much taking up your time to learn people who love electronic
Great teaching!
Thanks for passing your knowledge to me
Excellent 👍
I always struggled to remember the color code.. until i realized i already knew it!
On the machines i work on, the pneumatic lines use the very same color code, so there we go.. the day i connected the dots, i knew resistor colors :p
Bottomline : it's easier to remember it by practice rather than learning a table.
working a lot with vintage valve equipment i also have to think about voltage readings and inductance .infact you pointed to the problem of voltage with the start up circuits . inductance can effect osc or high frequence circuts where you would have to use carbon comp instead of carbon film resistors.
all in all a very good beginers guide to restors
Thank you. I have worked on valve equipment (I was trained to do it as well as semiconductor)
Yes when I mentioned the problem of high value resistors in start-up circuits that just fail with age, it occurred to me this is also true of valve circuits - the resistors are often high value carbon resistors with a high voltage across them, and they increase resistance in time when they 'age' but didn't mention it as I consider valve restoration/repair to be a bit specialised and there are some good very YT channels who dedicate themselves to this topic.
Yes you are correct, in some cases the inductance of a resistor is important. This occurs with low value wirewound resistors, which are basically a piece of resistance wire wrapped around a former, so will have an inductance as they are also a coil. This is important like you say in high frequency circuits, and also can be in high power audio amplifiers where a very low value resistor is in the emitter circuit of each output transistor - effectively to balance the current through each transistor in parallel, and the inductance of these resistors does matter. There are non inductive resistors made for this purpose and you need to replac wwith the correct type..
One thing I realised I forgot to do in this video was to show the schematic symbol(s) for resistors. I'll do that in the next video - Capacitors, and following ones.
Some great advice in this, thank you
My pleasure!
thank you for making these
Take a drink everytime he says yeah.🤣
Thank you. I'm just starting to learn about circuitry on my own. Any suggestions wher to begin
This is great! Do you have a book or recommend one to supplement this video series?
Excelente video thanks
Hi Richard great vid. Can you tell me if the kaiweets km601 you reviewed has adequate resolution to work well with the £1 sort finder you built? Thanks.
watching this video I did notice resistor colour bands its almost the rainbow colours without indigo in between blue and violet ok so black brown then Richard red of York yellow gained green battle blue vain violet with added grey 8 and white 9 on the end :) good way to look at it also gold then silver :) good lesson :)
Hello! I find your videos / your explanations really understandable and helpful! and my question is in no way a criticism! but please could you also make a video about Fuses!? Thanks max
Just what I needed
You're Welcome
Excellent! I didn’t know some of that about the numerical multiplier markings.🙏🏼
Question: does a parallel resistor have any impact on its precision rating? I was refreshing an old Sylvania tube tester and many resistors were two in parallel. Sometimes both had the same value sometimes not. The resulting values were not uncommon so I was wondering why that would be done. Thanks!
Possibly for the power rating
Coil fixes batteries, inductive coil is in laptop displays, and phones. In bios or power menu, this coil heats up and fixes memory effected batteries. Motor also fixes batteries. Only some laptop fans are capable to fix batteries. Resistors can have memory effect as factory default, to fix them in phones, solar power bank is needed, and could last for a day of pure solar charging.
Great
Thanks
Brilliant as always thanks. Do you use diode mode to test most circuits?.
No. I only use diode mode when I want to test semiconductor junctions (diodes, transistors etc)
Using diode mode will give a a lot of false readings - especially in circuits that have a low resistance (GPU, CPU VRM etc) as everything will look short.
Also diode mode can send enough power into the circuit to light an LED. I sometimes wonder if that is enough to damage delicate components that run on voltages as low as 0.7V?
I'll add this topic to the 'All you need to know about...' series (if people like it) and make a video 'All you need to use about using diode test mode'
This is exactly what my idea was - I also thought the new year (and lots folk of new year resolutions) was an ideal time to launch a beginners series 😉
@@LearnElectronicsRepairWow thanks. Very informative.
@@LearnElectronicsRepair Yes a begineer series would blow up. Pardon the pun.
Thank you
thank you !!!!
I just paused the video to like and make a comment. Excellent
Wonder what the next one is going to be, I'm rather excited for it.
Well it will almost certainly be this week - I'm thinking of making this a regular Friday thing for a while
@@LearnElectronicsRepair Brilliant! I really enjoy your videos.😃 Im glad your on youtube sharing your experience and knowledge. We appreciate your time. On a tangent, im glad you know electronics is not dead, far from it. I thought the same as the sale of stuff to learn electronics at home disappeared in scotland and probably the rest of the uk post 90's. Im so glad to see the young guys on youtube learning and doing the work. Amazing. Take care fella.
Hey what is a pull up and pull down resistor uses on laptops?
Oh, by the way, perhaps it is a good idea to also tell about the tolerance band codes.
I'm here because something broke, I may not be able to fix it but at least the videos are enjoyable.
Thanks
I have a surface mount resistor that is burned and can't see the numbers on it. Is there a way to find the value needed to replace it?
There's two ways:
1 - find the schematic
2 - guess
BIG PROBLEM , types of resistors , inductive / non-inductive ?
To my understanding , through hole & surface mount do not qualify as types - you can interchange without affecting the circuit ?
In many cases --- you can not change between inductive & non-inductive ?
Awesome ‼️...I thought I'm studying overseas from a short period of time. I learn a lot by just a one topic here, also there are other videos of you with another topic that I really need to watch and learn. Great video "Guro" teacher. It's really a great help for my study specially I'm a college student and with engineering Technology course. Thank you. ~🇵🇭
The multiplier is an exponent of 10, so the first resistor it is literally 4, then 7, then x 10^0 = 47 x 1 = 47 ( 10^0 isn't "nothing", it's 1 ! ).
Any real number with an exponent 0 equals 1...
Same goes for the next one : 47 * 10^4 = 470 * 10^3 = 470 kOhms.
It's simpler to say it's the exponent of 10. That's basic mathematics...
And for the gold and silver : exponents are -1 and -2, respectively.
Master please do all you need to know about mobile phone repair 🙏
hello, anyone know how much ohm is 0/4 resistor?, I see it in a boardview and schematic, it's written that way
DEKUJI ZA VASI PRACI
can smd resistors be replaced manually?
With a very weak hair dryer or heat gun, a tweezers, and a pair of gloves, yes.
Does it matter which direction a resistor is facing?
no
Awesome!
Thank you! Cheers!
I am very interested in flat screen tv repair that can be done using scavenged parts, as I have first dibs look at an endless supply of all types of these units. I need to pay attention now, so bye!👍

I have 2 burnt resistors, can't tell the colour codes.. It ends in gold that's all I can tell.
I wonder who came up with that weird acronym.
If Glaydis keeps dressing like that...
In Dutch the memnonic is:
Zij She

Gerrits Gerts

Billy Bloggs is innocent. Free Billy Bloggs.
Why not just WRITE THE NUMBER instead of all these colored bands and coding how bout this, black letters, 20K!
Original saying is racist.....
hard to understand because of the accent
i will use a different mnemonic…this is not appropriate in today’s world
The thing is the human brain tends to ratain shocking information hence the plethora of lewd mnemonics. You dont actually to voice them out loud 😉
Good ole Violet.
What was she wearing though? Lol
