@@cordongrouch9323 The original quote creator is "Locutus of Borg", and so Board sounds much more similar to Borg than Motherboard (it has too many letters to make it funny) And also, resistors can be used on any board, not just motherboards.
Yeah. One reason was that they didn’t expect you to tune out and listen to them for 30-1.5hrs straight, retain the information, and apply that information to a project. Don’t forget the fact that they lacked understanding that you could have a different learning style than what’s presented. It’s said clearly with icons to see and it isn’t overly verbose. It’s a great learning tool. 😂😂😂😂😂😂😂
Bravo on making a RU-vid short that actually tangibly teaches something and isn't just showing off the effect of something worth learning with a description of it.
You need to learn way more about chemistry and physics to understand how it works.* *how it works according to how we’ve agreed that the chemical and physical properties of matter work the way we say they do. In reality (if there even is such a thing) it probably works completely differently. But it only matters that our understanding is consistent and we can make reliable predictions based on it that have “real” world benefits. That it isn’t exactly a perfect description of how these phenomena “actually” work is not and should not be our concern since it would bring us nothing in terms of the benefit we would get from that understanding. Unless we are trying to defeat “god”, then absolute understanding of these things would probably be beneficial if we wanted to stand a fighting chance. I’ve gone on pedantically explaining this too far already so… byeeee 👋
@trippmoore I aint reading allat 😂😂😂 . (Just kidding, it was pretty informative and just want to make fun of people who say stuff like that and yeah I did read it all.)
@@trippmooreby definition reality exists. Whether or not we operate and think by it or are able to or pursuaded to follow it are a different story. There are many distractions to it to be sure.
@@trippmoorealso I DO agree with your analysis of our current understanding not always lining up with reality. That's a rare and forgotten scientific principle. MY definition of science btw lol: "Everything man THINKS they know about God's creation." 😉
i knew they had this shape because of the resistence in a heater, i had no idea resistors were just the same thing but smaller, i thought the resistance was based on the material they used
Same! After 4 + 2 years of “power electrical texhnician” school i still dont know whats the difference between amper and volt/watt. Graduated with 5/4 mark, what is near the best here. 🤣
Thanks bro I’m doing technology in school and we have to learn about all of this for a test and you just saved my ass with a 60 second video thanks again
I am sure most people here would know this but would still like to mention it because it was one of my fav. topics in resistors. Those color bands aren't to make it beautiful but in fact represent numbers that help calculate the value of resistor!!! BBROYGBVGW lol. I even made an acronym to remember this.
My man, if you try to write a scientific work and say shit like "it's narrow so the electrons don't fit through as well" you're gonna be in a world of pain
Maybe they teach it differently now, but when I went to school they didn't really teach it much like this. There was optional electronics course, which does teach circuit theory and stuff, but still not quite like this.
@@MsHojat i mean in my physics class we had a few lessons on the basics.. basically just this video but then you make a basic circuit using it, also learn the symbols and all that
I just understood this shit after 15 years... man! It makes sense now! Bc of the helical shape the electron has to go through a longer path and this is how it works! Fucks sake none of my teachers had show me something like this but i only needed this! Oh my gooooood!!!
Someone tries to tell for us,that the resistance only depends on the length of the path through the resistor? This is partly true, but the resistance depends on the material of the resistor. 1 kilometer of copper wire has an electrical resistance equal to one meter of tungsten wire. According to them, 10 mega Ohm resistor should have 162 kilometers of copper wire? Carbon layer, Metal oxide, Varistor,Thermistor, NTC, PTC are based on the electrical conductivity of the material from which they are made. The resistance depends very little on the length of the path, or the shape of the resistor. It depends exclusively on the material of which it is made...Do you understand? One metal oxide resistor 0.25 Watt, is about 1cm long. If it has a resistance of 100 megaOhm, it should have a 200 kilometer long copper or aluminum wire in it? So, the resistance only depends on the material, not on the length of the electron path ..Simple example: Iron has 7 times greater electrical resistance than Copper.
If you a doing basic circuit design you don’t need to know this. You just need to know what it does and what ohms law is. It could be a tiny room with tiny Lucy and tiny Ethel taking the electrons from a belt, wrapping them in a magnetic field the back on the belt. But they are In over their heads and can’t keep up and electrons are piling up and that makes the room hotter. That fact wouldn’t affect your ability to use them properly in a circuit.
Note that these are the old school type of resistors, which are rarely used in modern electronics. Resistors today look like tiny little black blocks, with their resisting value written on it (that old school color coding never made much sense)
Oh, they still have use in small and simple electronics projects. They are much more handy then SMD. And they fit quite nicely in electronics project connection boards. So I don't predict they will be out of use 😏
Well if you have a multi thousand dollar wave soldering machine, sure go with smd. If not, you will be using these. Not so much old school as you think.
@@NickFrom1228 There are SMD heating plates you can use to solder to the board. Look it up Note that hobby use isn’t the same as modern electronics. Of course you’d wanna go the old school ways if you’re doing things by hand in your garage.
In college, I would mention that you need to get the right wattage for a resistor, and my MechE friends would not believe that that's a thing. I'd pump 10 watts into a 1/4 watt resistor, and the end result was illuminating for them. Another 4 cents well spent!
There is a flaw in this explanation. Resistors dont make less electrons to flow. They just reduce the "force" with which they flow. Thats why you will see a voltage drop across the resistor but not a drop in the current flow.
What?? Of course you see a drop in the current, compared to 0 ohms... i.e. in an ordinary battery circuit. (Only with a theoretical and ideal synthetic current generator would your statement be true.)
Resistors don't limit the flow of electrons, they simply reduce the potential of the electrons to do work by making them do work to get through the component resulting in waste heat.
So does that mean the same amount of energy is taken from the source regardless of the resistor (or lack thereof), it's just that more (or less) of it is converted into waste heat?
omg the narrow part is genius but so obvious when knowing it, I always thought they put different materials in it to increase resistance which would be more complicated and expensive than just narrowing the path
Had a co-worker who liked to verify LED polarity with an un-ballasted 9V battery. Once the junction blew the top off the lens, causing him to declare, "Lo-owww - tech' LED!" He adopted the use of a ballast resistor after that.
I find it utterly fascinating that people figured this out and were able to design manufacturing processes that could pump out such precise little devices for pennies.
I’ve been writing a book in my spare time about Mechanics, Wiring, and Electrical Components and have been looking for videos that are exactly like this one, quick, concise, and straight to the point.
The colored bands on the resistor is also the reason why we have the phrase “the gold standard” as it is the standard percent error of resistance on resistors
@@Baneb1984 sure, but you said the reason we have the phrase "the gold standard" is because of the gold tolerance band on resistors. The phrase was used long before resistors were!
I learnt about resistors back in 3rd grade during a summer camp! It was all about electronics, making robots and programming. This explanation is exactly similar to what was taught to us. Much respect
Anther way to explain this is that they are like little tanks that hold THE MAGIC SMOKE and when them leak this magic smoke out, electronic things don't work anymore.
Resistors are often placed in series with diodes to reduce the current because the diode resistance is so low it'd immediately burn when given a forward bias.
@@808drumz9 Capacitors are placed between amplifier stages so the output dc bias network of one doesn't affect the input bias of the next. So does this capacitor "protect" anything? Imo no. It's just the way conditions are established for the circuit internally to work as intended. Same for the resistor. Otoh a varistor, fuse, or circuit breaker actually does protect against external factors that can do damage.
@@generessler6282 yes, well I guess the correct way of explaining it would be that the resistors cause a voltage drop so that the right amount of voltage goes across certain component(s) in the circuit, especially if you're stuck with some constant voltage source like a battery. But to the layperson, dropping the voltage so it doesn't burn stuff is kind of like "protecting" the stuff. It won't interrupt the current like a fuse would, so people in the industry wouldn't call a resistor a protective device.
In audio applications, the resistor can effect the tone of a device, so it’s a cat and mouse game of using a value that sounds good and designing a circuit that won’t blow up.
Wish i learnt these things younger. Never really understood any, i saw them and i picked them out of broken toys and my dad told me they were resisters and why they were needed, but never really registered. This brings a lot of fun memories back. Bless my dad ❤
This is used in many small power supplies. If the power supply is working normally, the resistance only gets moderately warm. If there is a short circuit in the power supply then the entire mains voltage is at the resistor. This causes the resistor to burn out and interrupt the current.
Reminds me of my grade 7 project. No, not the burning part but how I was amazed at the fact that with these components you could change the behaviour of things such as light bulbs. Back in a time when computers were massive and confined in secured rooms.
I used to use wire wound resistors and high powered caps to make ignition sources for fuses when I was interested in exothermic reactions once upon a time.
