Just had my final year exam with good grades. The Organic Chemistry Tutor has contributed to 60% of my success. Following these videos were of great help. I'm so grateful. Keep up this good job. Hope my college tutors will be like you.
A very thorough explanation however the last example was difficult for me to visualize. I think that it would be nice if he created a real world physical example using the potentiometer in the same way as did a real world example with capacitors and diodes. Anyway great explanation.
I have a question about why a potentiometer used as a volume control needs to have three lugs. It seems that in an audio circuit, the first lug goes to the input signal, the middle lug (wiper) is the output (coming out from the pot) and the third lug goes to ground. I assume this means that the balance of the current (the current that does not go out the wiper) goes to ground, unless the wiper is all the way at the "max volume" end and in that case all current goes out the wiper. Is that correct? What would happen if there was no connection to ground, and the current could go only out the wiper but not down the rest of the track and out to ground?
If you don't ground the lug, then it's not a voltage divider. That is, it's not putting a constant load on the pot and not acting like a real volume control. It's become a variable resistor in line with the output, which is essentially a tone sucker. No. Don't do that.
What is the difference application between the two arrangement of the circuits? (one by using all 3 pins of the potentiometer and another only uses two pin). It seems to me that both have the same function of varying the resistance. Or is there any other thing I missed?
Seems like A B C are used for turning up your volume or turning it down A and B applications where its only 2 are used in dimmable lights, so that you can go from 0% on 50% on them the max 100%
So which would I use to control the output from an air blower on a coffee roaster? Or temperature into the roast chamber? I’m a simple man please answer in simple terms. I think they’re both the voltage one, but I’m probably wrong.
Can I use some of the concepts described in this video for a video on controller aiming? I will link the video in the description and provide proper citation.
My setup calls for a 35K ohm pot. Can I use a higher value such as 40 or 50K. If I do, what will happen? Will I prevent signal from leaving amp and damage components in my amp? Thanks.
Thanks for the info,i want to know the diffent type of pots : Log, typeA,typeB, ETC. for example my audio amp. has a volume cont. 10k A , i cant find 10k A,i buy a 10k B if i intall type B, will it affect the quality or loudness of my amplifer? Tnx
At 8:14 you say the brightness of the lightbulb is directly proportional, maybe I'm misunderstanding but did you mean inversely proportional? Since if one value is changed down, the other goes up? I thought directly proportional meant if one value is changed up, the other value goes up, and vice versa. Thanks for this video! I'm not even in class, but I still learned something.
Can I solder a normal 100 kOhm resistor to a 100 kOhm multiturn potentiometer in order to get to 200 kOhm? Can't find a 200 kOhm multiturn potentiometer!
Potentiometers are adjustable resistors and are not variable resistors. The difference is that potentiometers or adjustable resistors have 3 terminals and variable resistors have 2 terminals.
That's true.if you move towards point A this means you are bypassing the resistor,which leads to a brighter light-bulb and vis-versa.l think he has reversed the situation.

Why does this dude know everything? I was learning trig from him yesterday, and algebra the day before, and now this? This dude is a legend.
Same thought dude hahaha he is so amazing!
This is basic electricity knowledge lol.......
@@modros6755 So? Having such a wide variety of educational videos is an achievement regardless of how advanced it is. Buzz off, neckbeard.
@@BadPractices its nothing special really. Its literally the first thing u learn if u go to a elektric school
@@BadPractices It’s the internet bud… relax, anyone can go on a plethora of sites and get the information needed to make an instructional video.

So how's your college tutors like? I'm guessing they're not similar to the organic chemistry tutor 😅
@@Milan-wc9te A number of them are, while the others aren't. They're just doing the job for the pay they receive 😅
Not all of them tho
Congratulations 👏.
I'm just starting the process here😅
@@reference_realistic you'll find it of great help, trust me. Good luck
He is a good teacher anyway. People are learning a great deal from him.
we needed the teachers like you sir, you just cleared my doubts within 11 mins, that doubts are not solved by daily 1 hour college lectures
Just got a job making these. This is my new favorite channel
I always feel like liking your videos a thousand times, sadly, there is only one like button. You always provide the best solution, you are my hero❤️
Thanks! The drawing was very useful in helping me understand how the cylindrical potentiometer works
Thank you so much. I learnt more in this one video that in a whole year of college. God bless you.
I would love you to have some videos about basic programming for beginners (HTML, CSS, ETC) just a recommendation though.
Check out sentdex or tech with Tim or Corey Schafer

Thank you. it is a great video.
Ooh, nice to know how the inner mechanisms of controllers work. Neat video!
I had no idea Mark Wahlberg taught science on youtube?!
@Luke Roman just another scammer youtube comment xD
Thanks. This helped me a lot
Thanks a lot for the explanation
Does a potentiometer only do series circuits or can you parallel circuits with them too?

Multiplication of total resistance by the V in will give us the V out? Can you explain this further more please? Thank you!
Thank you so much !

A and B applications where its only 2 are used in dimmable lights, so that you can go from 0% on 50% on them the max 100%
can you make a tutorial for audio distortion circuit ?
Also, does he go over the difference between these and the other one, the rheostat?
You the best

Bruh everytime I hear this man’s voice it calms me down lmfao
Bruh everytime I hear this man’s voice it calms me down lmfao
To control a small (like used in models/toys) brushed DC motor, would you use it like the light dimmer or like the other to control voltage?
Why do variable resistors only have 2 pins and potentiometers have 3? Why does a potentiometer need that extra pin?
If the circuit is connected from point A to C, I think the resistance should be the same no matter what you do to the nab. is that true?
Does that mean that potentiometers are tripoles?
Nice, thanks 😊
Can I use some of the concepts described in this video for a video on controller aiming? I will link the video in the description and provide proper citation.
So the voltage at the light is less than 6V? when dimmed, reduced current
My setup calls for a 35K ohm pot. Can I use a higher value such as 40 or 50K. If I do, what will happen?
Will I prevent signal from leaving amp and damage components in my amp? Thanks.

In 9:30 the c terminal is grounded
My friend, it's "puh·ten·shee·aa·muh·tr"
6 syllables
Not

Potentiometers are adjustable resistors and are not variable resistors. The difference is that potentiometers or adjustable resistors have 3 terminals and variable resistors have 2 terminals.
Great video just it's pronounced potenti o meter
5.56 i think u got it backwards . Swing to A should direct towards 12 V
That's true.if you move towards point A this means you are bypassing the resistor,which leads to a brighter light-bulb and vis-versa.l think he has reversed the situation.
Thanks for the video. Btw, it's pronounced po-tench-e-ah-me-ter.
... who's gonna tell him...
What
@@fabijanskrobar1750 that it's Potentiometer not Potentialimiter...
@@AmusementLabs I think it might just be his accent. I notice that he pronounces things weirdly in his other videos.
It's his accent lol. He doesn't pronounce it that weirdly or anything. In fact, I didn't notice it till you pointed it out
Hi! Why can't the vout be between points C and B?
it can. just switch the wires and everything will be mirrored.
and switches are just potentiometers that can't have a value other than 0 or 1
Finally, a technical video without the voice of someone from india... 😂
Just imagine you're my brother...
Im very early to learn
4:20
Pls respond I need this info..you have never responded to my question
Ask the question Anyone in the comments will Answer it for you. It doesn't have to be directly from him.
I've been happy before but not like this.
hoooooooooooo,,,,,,,,,that true
Who is watching this to figure out how a PS4 and Xbox potentiometer work
Definitely learned about potentiometers because of that curiosity. The controllers use two linear potentiometers to make them travel on a plane.
It's pronounced speed-ometer. Not speedo-meter.
Potenti-ometer, my friend
Can we have this video in Hindi or Indian English
😂 😂 English is English my friend. I'm from South Africa and Not a native English speaker but I hear him clearly.
Get lost Indian's
Don't bring disguise to the learner's..shut up or don't watch..The way he speaks and teaches is highly appreciated by all..
You are Indian or southafrican
@@montasimmayimmouno3345 shame on u
Am I the only one who finds his mispronunciation of the word "potentiometer" to be a bit off-putting?
