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.
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.
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
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
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?
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.)
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!
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
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.
I wish we had had videos like this available to watch back in 1992. It's a lot easier to understand now. The books we had were not enough to give me the drive to learn.
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.
Resistor is the only good lesson in my study with physics. Though I forgot the formula, I remembered being focused to it and getting good scores. One wrong value from any of the bands can already damage the circuit. Very important little guys.
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
This trend of trying to make RUclips shorts replay seamlessly is a bit much for this video. Starting out with “it burst into flames” just makes the start more confusing than it needs to be
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.
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!
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.
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.
The function of a resistor is to limit the current in various parts of a circuit - the purpose is not to protect components as a primary function, since fuses are specifically designed for that purpose. A resistor isn't there to protect a transistor, but to limit the current flowing through the base (b) which controls the larger current flowing through the (c) to (e) region - similarly a resistor value is chosen to limit the current flowing in an LED depending on the applied voltage, so that the brightness will be appropriate in an application and within the manufacturer's specification. Resistors are passive current control devices. Modern resistors are metal-film and generally smaller than the older carbon type resistor.
"the purpose is not to protect components as a primary function", While this is true, I'd like to point out fusible resistors do exist for that exact use case.
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 ❤
Now this is how things should be explained. No goofy music, no tooling around. Just the straight dope. What it is, what it does, and how it can be used.
You explained it in easy way , Im currently studying the electrical chapter in science and it will definitely help me in exam and i can write answers on my own 😊
For carbon resistors, size the such that the operating wattage is less than 80% of its rating. Running carbon resistors hot causes them to degrade. As they age the resistance will slowly drop, which in turn increases the current and wattage, thus degrading the resistor faster.
The primary mechanism by which energy is dissipated in a resistor is through collisions and interactions between the drifting electrons and the lattice structure of the material. As electrons move, they collide with lattice atoms, transferring kinetic energy to the lattice in the form of vibrations (phonons). These collisions impede the flow of electrons, and the lattice vibrations contribute to an increase in temperature, representing the dissipation of electrical energy as heat. In summary, while the drift of electrons constitutes the electric current, the energy transfer and dissipation in a resistor occur through collisions between electrons and lattice atoms, leading to lattice vibrations and the conversion of electrical energy into heat.
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.
Electrons don't collide with atoms, they transfer kinetic energy to other electrons, a behavior that looks like a collision, when a circuit is closed, causing a domino effect of kinetic transfer. The kinetic measure of electrons, called current, must balance with the potential energy in the battery as voltage or electron voltage and the resistance or magnetic capacity of the resistors, transistors, switches, modems and even wires. Flames of fire are made up of electrons, so if there is a build up of electrons in one area, when the voltage is higher than the resistance ability, a flame is created.
A resistor saved my life once. When I was about between two and three I crawled under a chair and stuck a resistor in an electrical socket. The doctor said anything else and I would have been Dead. Still melted to my fingers, blackened my arm, and made my hair stick straight out.
it's a misnomer that electrons actually move like bugs around a light bulb at night - they don't - "current" isn't "flowing" electrons - even in a full scale generating power plant, electrons barley move inches over time.
Very good video with a great explanation. It could have been longer with some additional math showing “here’s how you determine the needed resistor, maybe the reasoning for multiple resistors, etc., etc., and I’d still have been thrilled with the video!” Great stuff!

Ur explination is much better than any teacher out there
The function of a resistor is to limit the current in various parts of a circuit - the purpose is not to protect components as a primary function, since fuses are specifically designed for that purpose.
A resistor isn't there to protect a transistor, but to limit the current flowing through the base (b) which controls the larger current flowing through the (c) to (e) region - similarly a resistor value is chosen to limit the current flowing in an LED depending on the applied voltage, so that the brightness will be appropriate in an application and within the manufacturer's specification.
Resistors are passive current control devices.
Modern resistors are metal-film and generally smaller than the older carbon type resistor.
"the purpose is not to protect components as a primary function", While this is true, I'd like to point out fusible resistors do exist for that exact use case.
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 ❤
I found this channel yesterday ,really nice, especially as I'm trying to pick up some of this as a hobby. Thanks for making this content.
Now this is how things should be explained. No goofy music, no tooling around. Just the straight dope. What it is, what it does, and how it can be used.
Resistors are used to drop voltage and limit current flow. Was the specific definition we used in my digital systems course in college.
You explained it in easy way , Im currently studying the electrical chapter in science and it will definitely help me in exam and i can write answers on my own 😊
For carbon resistors, size the such that the operating wattage is less than 80% of its rating. Running carbon resistors hot causes them to degrade. As they age the resistance will slowly drop, which in turn increases the current and wattage, thus degrading the resistor faster.
This video explains better than my teacher
Finally after 28 years with university and highly I now understand what a resistor does and how it works

The best explanation of why resistor is useful: the why and how of using resistor.
The primary mechanism by which energy is dissipated in a resistor is through collisions and interactions between the drifting electrons and the lattice structure of the material. As electrons move, they collide with lattice atoms, transferring kinetic energy to the lattice in the form of vibrations (phonons). These collisions impede the flow of electrons, and the lattice vibrations contribute to an increase in temperature, representing the dissipation of electrical energy as heat.
In summary, while the drift of electrons constitutes the electric current, the energy transfer and dissipation in a resistor occur through collisions between electrons and lattice atoms, leading to lattice vibrations and the conversion of electrical energy into heat.
I only knew it resisted. I did not know what. Thank you! I learned more in a few seconds than a two year apprenticeship😊
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.
that was actually an awesome clip to happen upon, thank you for that great explanation 👍
Fun fact, lights also work as resistors. The basic idea is a resistor reduces energy in a circuit by releasing heat or light, which a bulb does
I think this is the best example how the rezistor work and how to calculate the value od the resistor!! Thanks! 🙏
See the full version of video, so much more detail
Teaching made easy. Need more videos like this
Electrons don't collide with atoms, they transfer kinetic energy to other electrons, a behavior that looks like a collision, when a circuit is closed, causing a domino effect of kinetic transfer. The kinetic measure of electrons, called current, must balance with the potential energy in the battery as voltage or electron voltage and the resistance or magnetic capacity of the resistors, transistors, switches, modems and even wires. Flames of fire are made up of electrons, so if there is a build up of electrons in one area, when the voltage is higher than the resistance ability, a flame is created.
“And so, resistance increases.” 😮💨 felt like a bar to me, I can’t believe explained it that easy to me too
A resistor saved my life once. When I was about between two and three I crawled under a chair and stuck a resistor in an electrical socket. The doctor said anything else and I would have been Dead. Still melted to my fingers, blackened my arm, and made my hair stick straight out.
Bro is explaining so simple Than compared to my Professors when I was studying ECE in Engineering college .
I swear i'm learning more from these shorts that i did from 4 years of school
it's a misnomer that electrons actually move like bugs around a light bulb at night - they don't - "current" isn't "flowing" electrons - even in a full scale generating power plant, electrons barley move inches over time.
Can we appreciate how accurate this is?
Finally someone explained how it works
I know I'm fucking dumb but this shit made me feel like Einstein for only 1min
OK, is that ment to be a looped video? You done perfectly!
Explained resistors better than my physics teacher.... Thanks :)
Glad it helped, check out our full tutorial, soooo much more detail. Link bottom left
Nice to see someone not using the water flow analogy again.
One of the best uses of a loop I’ve seen
Damn, that explains more than all of my years in school, thanks
Thank you for explaining it this way
Thank you I've been wanting to know what this was. Great explanation!
Very good video with a great explanation. It could have been longer with some additional math showing “here’s how you determine the needed resistor, maybe the reasoning for multiple resistors, etc., etc., and I’d still have been thrilled with the video!” Great stuff!
RUclips limits the short to 60 seconds, so we can't fit more in. However, link bottom left for full tutorial on calculations
@@EngineeringMindset Excellent! Thanks! I did not notice that but will go there now. Good content, absolutely.
Learning has occurred. Good Sir😊
Easiest to understand explanation of LED that I ever had
I have so many and had no clue what they did, thank you
Could also be a metal oxide layer, which is generally more precise and offers better heat resistance. 😊
It's called the 'Joule effect'. Similarly why capacitors get hot during normal function.
And we can calculate the *Resistance* of the resistor with the colours in it. It is called *COLOUR CODING OF RESISTORS*
I love learning stuff like this
This’ll help with my math class, thanks, makes more sense now
