it's so hard to find a video without the mumbo jumbo added in the middle. I just needed to understand the real basics of potentiometers and not the formulas and materials around it. this was a perfect explanation. thankyou.
Mumbo jumbo
Exactly
I can't believe how much I've learned watching your videos. Great work. Thank you!
Thanks so much, I had to watch about 18 other videos before I finally found one that actually was helpful, now I know how this component works. THANK YOU!
I've watched dozens and dozens of videos but yours was so much easier to understand in such a short time. I'm a master instructor in TKD and you certainly have the right method and skills for teaching. Thank you.
Best explanation I found after 8 videos trying to show without describing the internal workings.
That was very, very well done. I normally need something explained to me several times and once I get it I always remember and have instant recall, but you explained this so well, I got it first time. That is a talent. Thank you. Subscribed and Liked.😊👍
Best explained! This is what I needed exactly. The practical explanation!
very good way of explaining things. Thanks, you've helped me to understand this much more easily :)
An Excellent tutorial. Easy to follow and to the point. Thanks
Thanks a lot, this exactly what I was looking for.
And I can say for free that I have understood most everything surrounding Potentiometer
Once I understood on my own how it works TH-cam started sharing these videos to me. Too late TH-cam! But it confirmed my speculations. Thanks for sharing.
Having found this video helpful and easier to understand than others, I like and subscribed.
I enjoyed your video. It was very helpful. Thank you!
Thanks for your videos...
You are a treasure from TH-cam...
I just fixed my rotary taper potentiometer ..
From my GT series thanks bro..
Thank you! Your video is truly helpful.
Thank you sooo much. Now I've understand, what a Potentiometer is. No video in my country (Germany) could explain it. Your videos are so great for newbies like me ^-^
Great video. Just found your channel I wish you would post more often you really have a way with teaching

very educative. Thank you regards
awesome video
Great video
Good Explaination mate
excellent video. thank you
nice one well done
ur doing easy studying electronic nice work ur doing keep it up
make video on open circuit and short circuit
Can I use it for an led setup. I'm adding lights to a tiny brass lantern I found.
What a GOOD ass video man thanks
thanks realy u make it easy
Thank you sir very nice gide & very nice best information potentiometers teaching video.👍
thanks a lot i subscribed
Nice content
explicit and easy to understand.
Nice video. more video lika this
Thank YOUUUUUUU !!!!!!
At 3:03 i facepalmed (the aha moment ) and understood the whole thing logically, more material more resistance the wiper is the output easy now i'm dumbfounded why other vids fail to convey this message... For somebody who has no basic idea or wrong way of thinking about electronics/wiring it seems so complicated.
Thank you again for this great explanation!
Thank you!
ThInk I so muck h interesting and awesome!
You draw very well
Excellent
some pots are motorised like on a mixing desk. sliders and dials can move on their own
good one
thanks a ton!
thank you!
I love this video! I ran across "potentiometer "doing my homework, this is a great video for understanding the function of it! Not only did you describe the interior, but you also demonstrated the measurement with the multi-meter, thumbs up for you. I'm going to check out more of your videos!
Hello there! Could you please give an advice how to scale a potentiometer for volume control? How big resistance should I choose? I saw a lot of different examples from 50Kohm to 500Kohm and I did not recognize any pattern or rule in the builds that I can use with common sense.
thank you good sir
Hi I have a faulty B30k potentiometer will a 25k or 50k work on a mobility scooter speed control thanks Jeff uk
nice lessons these video are really helpful thanks
one question what is differents between potentiometers and trimpots
They are the same thing, trim pots are just made for precision
Great video Thanks I am making a variable resistor to fool the computer of a 2008 Honda Odyssey so that the VCM (variable cylinder management )doesn't engage because it causing the engine to burn alot of oil. When engine reaches operating temperature and there is not a heavy load the VCM turns on which means it turns off some cylinders but it also created a vacuum sucking oil into the cylinders and burning it (big cloud out the tail pipe) I bought a bochen 3296 trim (blue square) and i dont know what pins 1/2/3 are for?? Is it the same as you spoke of in this video?? I going to use a 200 ohm and adjust between 84-120 depending on the season. Will the trim pod potentiometer with stand engine bay temperatures or should i put it inside the cabin?? This will trick the computer in to thinking the engine never reaches operating temperature. Thanks for your help Rush
Excellent! Simple and clear. I understood everything (he says as he’s about to ask a question which proves he understood nothing!) so is a dimmer light switch in a house or even on your car dash for the instruments a potentiometer is that different?
good video
Explanation skills are damn good
thanks
Thankyou, I can inderstand what happens when I am using the potentiometers on my electric guitar. Can they be wired together as in series or parallel for any practical use?
i would like to know if the potentionmeter does the same work as rheosta?
Thanks
I have about 300 soft white LED strings wired in opposite polarity strings. The cheap driver/transformer (China) keeps cutting out and over the years the kids have snapped odd wires. I have sorted the strings into runs of 10 x 30 and want to drive them ALL from one power source. I have a model railway Gaugemaster EN60 742 controller with 3 stable outputs:- 2x 0-12v DC rated at 1A 12VA max per track and a single AC supply rated at 16v but no amperage is given on the unit. How can I make ALL the lights work continuously. Obviously the DC supply only makes half the lights work and I'm not sure what value of resistance to use to step down the 16V AC voltage to 2v? for the LED's?. Could I use a variable resistance potentiometer? I'm not a complete novice (O level Physics 1986) butI would like some assistance/advice/input for this project Am I better off with a LED driver???
so which of the 3 connectors of the potentiometer do you actually connect to the circuit? Would the middle pin be used as the positive end and either of the side pins as the negative end? And from the end of your video it seems that you only use 3 of the pins if you want to use the pot as a voltage divider, ultimately making it a junction
A potentiometer is not a polarized component. And yes, 3 pins are used to create a divider, splitting the voltage between two pins
thanks
I'm actually working on a circuit right now and I grabbed a random potentiometer so idk what its resistance range is, but I have it connected to a 9v battery and a dc motor (unknown specs as well) and connected the middle pin and one of the side pins to the circuit. However the motor only turns on when I have the knob of the potentiometer positioned at its max position, when I turn the knob away the motor instantly turns off, it doesnt slow down or anything. Could you possibly explain this?
its better on EveryCircuit
I wanna use one to vary the current by increasing/decreasing resistance in a resistor type heating device.
Very useful video. Could u give us practical demonstration with it. Thank you.
I went to your patreon page but there is zero content there?
I have a potentiometer and it labeled like this B10K 270 what is 270 stand for
Other uses of potentiometer include fuel gauge in cars, also throttle body sensor, speed gauge and RPM gauge.
hey do u have a video on how potentiometers are used to measure potential difference in a circuit??
How do you determ8ne what ohm pot to use for music volume rca adhustments?
ive found one of these , thought i could use it to connect to a small motor, can i? to make the motor variable speed?
Very inefficient way of varying speed to a motor. You can do it but you'd need a high power potentiometer to do it. DC motors are usually controlled using pwm to vary the voltage to the armature.
very interesting to know there is a site like this but I would lie to know and see how to make one using resistance wire and what type and size of wire is it kanthal or nichrome wire to use, can you show or demonstrate please
They're called "Trimmer" pots, when they are used in a circuit to make adjustments.
Would the demonstration have worked equally well if you have attached the meter to the left and center pins instead of center and right?
so i have have 24v DC adapter and i want to connect to led lamp(also 24V DC) with potentiometer to adjust brightness of led lamp. what kind potentiometer i have to use? and how to connect to adapter to make it possible?
Great video, but why are there three wires running around if the wiper is only in contact with the smallest diameter one?
Watch the video again: The wire connected to the "wiper" is the output. How would anything be output if not for another wire to input something? It's not as if the "pot" creates current "out of thin air"! The third wire goes to ground. The whole idea of the pot is to divide what is input between the output & ground: If the wipe is at the start of the carbon track closest to the input wire, all of the current avoids the track and passes into the wiper & out...no resistance. When the wiper is situated at the other end of the track, everything going out the output wire is exposed to a resistance equal to the value of the pot, and the rest goes out the ground.
So, there must be 3 wires: in, main output & ground. Consider that the same amount of current flows regardless of whether if ends of going out the output or goes to ground. Theoretically, a resistor can work without a ground, but then the total current flowing thru it would be only what goes out the output. The effect on the circuit would be very different.
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.
it is excellent domo of potenciometer. Brother can you give demo of servo mechanism. i will be benefited. thanks
Gotta love the sound of Sharpies on paper....
please can someone tell me what are the possible errors of the potentiometer experiment
why wouldnt the resistance be across the wiper? is the resistance on wiper assumed to be negligible?
What is the difference between a rheostat and a potentiometer? Don't both of them offer variable resistance in a curcuit?
The value of the resistor would be the max, min or med resistence acording to Ohms Law? hope this came across... Thanks for the awesome series.
Your question does not make sense. Perhaps if you could rephrase i will try to answer.
Fair enough, what refference does one use to calculate the value on a potentiometer? - The Pot comes with a value right?! 1K, 100K, 500K... is this value its max, min or avg. Thanks.. hope I made it somewhat clear, not english spoken here.
Much better phrased. The value of a potentiometer is based on its max resistance. So a 10k pot has a max value of 10k. Min value of all pots are usually 0Ω.
Dumb quenstion right?! Thanks again, hope you keep uploading soon
+David Sanchez the only dumb question is the one that isn't asked. You are welcome my friend.
Hey its good work...can I communicate you in other option because I have a question
Nextelectronics is reuploading your videos!
Jim brought me here :D
Hello. May I ask you what is the best circuit for a 9 vdc to 27 vdc booster with integrated circuits? It would be just great if you have a link to the circuit at EveryCircuit.com.
Everycircuit.com doesnt support Integrated circuits. However, check out the LM27313, a boost IC which will support your 9v input and boost to 28v. The first page of the datasheet for this IC gives you a schematic for its typical application. www.ti.com/lit/ds/symlink/lm27313.pdf
Thank you very much!
Do you know a bout a good open software simulator for ICs, etc?
Not sure about simulating this particular IC but maybe similar ICs in circuits.io
Thank you.
I would like to know some time your take about patented Tesla´s radiant energy receiver versions.
I like the way you teach. Keep going.
circuits.io does not have the pots
So what's the difference between potentiometer and variable resistor?
There is none. However a potentiometer becomes a rheostat when the middle pin is connected to one of the other pins. Edit: actually a Rheostat and a variable resistor are the same apparently. Edit Edit: I have no Idea anymore
Why do we sometimes see a negative going to the third terminal?
then what is difference between a regulator and a potentiometer ? regulator which used in fan.
