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!
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)
Great video as always! The only thing I'd add is, that the wattage of a fusible resistor should not be changed up or down as it effectively acts as a fuse and protects other parts of the circuit. With increased wattage more power can go through before breaking the resistor and thus can damage the circuit.
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!
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.
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
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,
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.
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!
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
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 :)
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!
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 😉
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.
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.
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 ?
@@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.
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.
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. ~🇵🇭
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!👍
