Crazy I went from being a communication major with a emphasis on broadcasting and a few classes away from my BA, then I decided I needed some extra cash and was curious about HVAC this past year and holy moly haven’t looked back since . Changed my major to ECT /HVAC been watching so many videos on TH-cam feel like a little kid when they discover what a trampoline is I can’t get enough hahahaa I’m 26 to never to old to pick up a trait . All young man look into a trait unless you are stem major . Love this industry
I tried so many to understand what is this resistance and I failed. I watched many videos but they failed to explain this too. Finally I tried to built up a my own theory to explain this but also failed😂 BTW this amazing and short video explained me what is recistence in just few munites. Appriciate the creator who uploaded this content! Thank you so much! ❤❤
If the marble is electrons, actually, electrons can NOT flow out of their positions, if that is the case, we never have solids. The analogy is: push some marbles in at one end, because the marbles are so squeezed, the other end will have some electrons out.
Just a question. Does resistance really have to do with the length and area??? Or is it just that more length ultimately means more collisions? And more area means less collisions? Or does it really have to do with the distance and area? From I what I always understood resistance is always caused by collisions with other atoms.
sorry but its wrong at 0:44 flow of electrons is not current current flows in a direction opposite to the flow of electrons very helpful video thanks a lot
Resistance can narrow the flow to the smallest quantum input but then why don't we increase the resistance to perceive beats for a pitch oscillator the less you resist more lower energy is perceived how can they both be Quantum they vary approach
Hey Nathan. Your video is great, perhaps, nor one other best videos out there. I would like to mention your video in my blog. Please respond to this comment.
If resistors were 100% efficient.. Resistors 'bleed' off electrons as heat. Like a dam overflowing with water and losing power sense that water will not be used to turn a turbine.
Resistance is a horrible concept. It’s based on the observation that different components need different p.d.s across them for a given current to flow through them. This is explained by some sort of mechanical analogue - it’s like walking through mud, or struggling to get through a crowd, or going through a constriction in a pipe, or some other visualisation that involves some sort of ‘resistance’ to the flow of current. The key thing to realise is that electrical resistance is itself a metaphor, and the metaphor brings with it all sorts of implicit associations for the unwary to trip over. Even if teachers understand all the subtelties, students won’t unless you’re very careful. Here’s a very quick summary of the problems. 1. You can’t separate the idea of resistance from how power supplies respond to changes in resistance. So any mechanical analogy for resistance also has to correctly include power supplies. Power supplies are designed to keep their voltage constant, and respond to changes in load by delivering different currents. This is how you can design millions of different devices that can all run off the same kind of battery, even though the batttery has no idea what it’s going to be connected to. 2. When we experience a resistance, for example walking through mud, we may walk slower, but we also tend to try harder - we struggle. This implies that batteries have to work harder to make ‘the current’ flow through the resistance. (This is where the rope loop model is particularly guilty of reinforcing misconceptions.) In fact, power supplies respond to an increased resistance by working less hard - they simply provide a smaller current. Power supplies don’t try harder to ‘overcome’ a higher resistance. 3. There isn’t a ‘the current’ that the battery tries to make flow while the resistance pushes back. If the resistance is higher, the power supply responds by keeping the p.d. the same, but reducing the current it supplies. 4. The place where energy is shifted quickest is where the resistance is biggest, but increasing the resistance decreases that rate, because the current decreases. It’s actually more subtle than that because it depends on whether you’re dealing with a single component, or several components in series. If you increase the resistance of a low resistance in series with a high resistance, it shifts energy quicker at first as it takes a bigger share of the voltage, and then less and less as the effect of the decreasing current dominates. 5. The speed of charges tends to increase where there is most resistance, not decrease. Even though the current is the same everywhere in a series part of a circuit, the speed of charges tends to vary with material and diameter. Narrow wires (like in a bulb filament) need to have faster charges for a given current, which is why they interact with the lattice more, and energy is shifted there, rather than in the leads. If you can find a mechanical analogue that has none of those problems (and is simpler than the actual definition of electrical resistance), then please let me know. That’s why I tend to stick to the definition, that it’s simply to do with how big a p.d. you need for a given current, but without really trying to explain why.

What?
This is one of the better visual aids I’ve seen. Thanks!
thank you so much, its hard to understand resistance with just imagining what resistance is
Agreed
Fantastic visual demonstration, it really aided my understanding. Thank you.
this was great please do more stuff like this

Great video! So useful :)
Awesome explanation Sir, please please please make more such videos. This video was very very helpful in understanding the concept of resistance.
Now the concept is clear. Many thanks.
Thanks! I am using your ideas to teach students with visual deficit
Very helpful for understanding .
Does this mean electric current decreases with increasing resistance, does anybody explain? while potential falls across resistance
非常棒的解說，Thanks。

Damn, this video is underrated
Can so,even explains why does current is same in series even after passing from a resistance.
Amazing!
Very helpful please make more such videos
your video is great, why don't you continue
Good vid... Electrons enjoy the path of least resistance... But they constantly bump into each other..
Thanks for the video, it was very instructive. Are u Maltese? I know that Bartolo is a Maltese surname but u sound Ozzy ( writing from Malta)
amazing video, thank you
great explanation!
It is really helpful in studies
Damn that was fun
Mindblowing
R=pl/a. Equation would need a density factor. Such as weight

wow!!! amazing explanation, i couldn’t understand the book explanation but your visual explanation helped a lot, thank you sir :)
A+
Thank you❤
Ooohhhhj!!! Now I get it!!
Explained well!
sorry but its wrong at 0:44 flow of electrons is not current
current flows in a direction opposite to the flow of electrons
very helpful video thanks a lot
It was just to explain
Thats brillo that matey
beautiful explanation
If obstructions increase on increasing length , they should also increase on increasing A , which should increase resistance ?????
If your increase length ,the resistance will improve
Resistance can narrow the flow to the smallest quantum input but then why don't we increase the resistance to perceive beats for a pitch oscillator the less you resist more lower energy is perceived how can they both be Quantum they vary approach
awesome job nathan helpful as a donkey on a cottonfield
Good explain 👍
Ok.....so how do we play marbles?
Hey Nathan. Your video is great, perhaps, nor one other best videos out there. I would like to mention your video in my blog. Please respond to this comment.
So resistance is a property of matter?
Thanks a lot
BUT current flows in the opposite direction to the flow of electron🙄
My science teacher sent me here
super😃👍
Is resistance important?
Brother can I use your animation?
Does this decrease watts?
Thanks
But we thought that current remains same before and after passing through the resistor and how it is possible
This does not mean current don't reduce it reduces but from overall circuit
It does, but the current is less 'potent' since electrons have bled off at resistor.
Superb
post more videos
that 1 marble didnt wanted to flow
