- Resistors are the most common component in electrical circuits. Have you ever wondered why? Let's take a look at what resistors are and how they work. Resistors are made of a certain material with a known conductivity, and depending on the conductivity it will be able to slow electrons down. This causes a voltage drop across the resistor. If we were to skip using resistors all together, our circuit would either melt or explode. These fascinating components as simple as they might seem are the most important part of any electrical circuit design.

I have been trying to find why a resistor is so important for hours and your video was the only one that truly explained that. Thank you so so much! Great video!
Love the speed limit analogy, the concept of resistors and ohms just wasn’t clicking until watching this video. Thank you so much!
You explained better than our school teacher nice work dude.
All along I was thinking "But, once the LED is fully open it imposes almost zero resistance". I must say the ending of this short video brought peace to my mind:-) Excellent video as always.
Osm lacture sir ,
I am from india and this is the best explanation keep doing.hard work
Im trying to get into electronics and I know literally nothing, if you look up electronics for beginners they tell you useful things but not all the necessary info. Thank you for the help.
Coolest way to explain electronic in depth
Woah!
U killed it in here
✨✨✨
Thanks!
Keep on going dude, this channel will blow up soon, your quality is top class.
Remember us when you get famous though.
Thank you. I really enjoyed the mobile electron demo. Creative and fun for learning.
Thanks for the explanation!! I appreciate you for your hard working to make us understand this.
Very helpful! Thank you
Very good explanation!!
Nicely explained!
Very well done. I'm gonna go check and see what other videos you have now.
Excellent stuff! Studying for exams, appreciate this!
This was awesome! Thanks
Great video!
Very nice explanation
great video man!
Good explanation.
Great explanation🤝
Thanks so much
Dude awesome video👍
Actually resistors don’t slow the speed of electrons. That’s why the CURRENT is the same all around a loop. There is a voltage drop as explained, however. Search YT for more info.
Thank you very much sir
More than the content i enjoyed your creativity. Nice 👍
Keep up the good work
What the great video!
You are the best
super explanation sir.....
Thank u ,iam really understand the concept of resistor ,and I love my physics chapter 🙏🙏
Thanks Bro...
Very nicely explained! Sub from India ❤❤❤
Woah ❤ , that's Cool
Yay for resistors!
Thank you sir you saved my grades
Easy I understand it now in less than 5min 😁
I was hoping that you would build the circuit again with a resistor this time and explain why this is working.
for some years now (because i dont want to say decades) generally understood what a resistor is and does and its general purpose but you pulled back the curtain on its process. like you showed me a different picture of it now its clear. i not only umderstand but i am one with the resistor.. too much?? thanks , sub'd
Loved the video❤️
Hare Krishna prabhuji 😊😇🙏❤️
Gold video
First awesome video of y tube
Best reactions

me who wasn't shown it in school cuz I'm not in high school yet: *do I not exist? Oh no.*
God bless you!
you need more subs
Yes
thankkkkk youuuuuuuu so muchhhhhhhhhhhhhhh
oooh so that's why we use vaccum tubes in many things back in the days
I've been looking for an answer to this question. If you have a 3-volt circuit, and an LED that runs fine on 3v, do you still need a resistor. I ask because I am repairing a pair of small desktop fountains that have a couple LEDs and a water pump in them. They run on 2 AA batteries, or a 3v PS. Yet when I opened up the units, they still had resistors in line with the LEDs, and the water pump. Are they required?
What is the direction of flow of electron?
Positive to negative or negative to positive?
Can you explain how to determine when you need a resistor and how high the ohms should be...Loved this video, clear concise and explained beautifully. Thanks
If you ever need to limit the current to a certain amount of amps or miliamps, use ohms equation of r = v/i where i is the amps needed to have to perform the task.
@@siliconnitride7029 yes. That I understand but how do I know if I need to limit the amps?
You would need to know the current design of your particular circuit. For the LED circuit I looked at the current rating of the LED I was using. Also keep in mind that the resistor has a limit of how much current it can handle as well(before it burns up) this information will be provided on the datasheet in terms of how much power it can handle 1/4w 1/2w..etc.
Thank you for something that has bugged me or eons.
Fucking thanks! The best explanation yet!
Resistors reduce the flow of electrons but do not reduce the speed of electrons.
But the lamp Will only use the current that it needs? The resistor Will make sure the votage is low enough to match the lamp when the lamp uses current?
Why do the electrons travel faster and faster once the circuit is closed?
I literally connected a 3v lamp into ac (my lamp's socket) and the breaker freaking popped idk what happened help me pls
Where are you from ⁉️
So I plugged in a plug without wiring it up first. So no resistance. And the outlet started to smoke and spark. Oops. That's why I'm here trying to understand what I did wrong. I thought it was the outlet. 😬
resistors doesn't slow does current
