What is the difference between 1k and 10k potentiometer?
The numeric value tells the value of resistance. 1k means that the pot will provide resistance up to 1000 ohm. 10k & 100k means it will provide ten times and 100 times more resistance than 1k, respectively. The lesser the resistance value, the more the current drawn by that pot.
What is the difference between 10k and 100k potentiometer?
So a 100K potentiometer has ten times the resistance of a 10K potentiometer. Which one you would choose depends on the application—it's often a tradeoff between some form of the following two factors: At a given voltage, the 100K pot will draw less current, which could reduce wasted energy and improve battery life.

Can I use 100k potentiometer instead of 10k?
Than can result in lower distortion when the driving stage is rather weak in clean current delivery. That means, for high input impedance of input stage, use 100k instead of 10k.
Can I use 10k potentiometer instead of 50k?
It will work in a way that you will increase input resistance, but you will loose gain. Adding 10k resistor before the 10k pot will lower signal by 6dB. Depending on your source, you may not need any adjustements at all and 10k pot will work equally well as your 50k.
What is K in potentiometer?
A potentiometer consists of a long wire with uniform area of cross section which is made up of manganin or constantan. Potential gradient (K) is the potential drop per unit length. It is calculated as V/L, where V is the potential difference between two points and L is the distance between two points.

How do you choose the value of a potentiometer?
Select the correct range. A potentiometer does you no good if it covers a range of zero ohms to 100 ohms but you need it to operate up to 1000 ohms. Conversely, if you need to make adjustments of 10 ohms, you'll find a range of 1,000 ohms too coarse to adjust.
How do you choose a potentiometer for volume control?
In general, you want the potentiometer to be as small as possible without putting too much of a load on the source. A quick rule of thumb for selecting the resistance of a potentiometer is that you want the input impedance to be an order of magnitude (10 times) higher than the output (source) impedance.
What does 100k ohm mean?
“100r” is something people type because the symbol for ohms, Ω, is too inconvenient; it means 100 Ω. “100k” means 100 kΩ or 100,000 Ω. 100k would be 1000 times too large. Stanfree January 15, 2021, 2:10pm #3.
What is the difference between 50K and 100k potentiometer?
100K and 50K pots are the same, their division factors will be the same at a given rotation position. The difference between the two pots is the overall resistance they present across the source.

How potentiometer is connected?
A potentiometer has 3 pins. Two terminals (the blue and green) are connected to a resistive element and the third terminal (the black one) is connected to an adjustable wiper. The potentiometer can work as a rheostat (variable resistor) or as a voltage divider.
What are the types of potentiometer?
Potentiometers can be of two types, linear and rotary. A potentiometer consists of four main components: two fixed terminals, one moving terminal (called the wiper), a resistive strip or track, and the housing.
Does a potentiometer change voltage?
A potentiometer, or "pot" is a variable resistor with three terminals and a shaft that can be turned in either direction. Using one of the end terminals and the wipers, create a variable resistor to control or adjust current. Use all three terminals to create a voltage divider to control or adjust voltage.
What type of sensor is a potentiometer?
Biomedical Sensors A potentiometer is a resistive-type transducer that converts either linear or angular displacement into an output voltage by moving a sliding contact along the surface of a resistive element.
What is a 1k potentiometer?

What is the symbol for a potentiometer?
The character symbol of the potentiometer is "Rp". A potentiometer is a type of rheostat. Usually consists of a six-leg potentiometer resistor body and a rotating or sliding system, that is, a moving contact moves on the resistor body to obtain a partial voltage output.
Why is a potentiometer called a potentiometer?
It is called a potentiometer because its function in the circuit is to obtain an output voltage that is related to the input voltage (applied voltage). It is usually manufactured to maintain its original characteristics no matter how long it is used.
Is a potentiometer a resistor?
The potentiometer can be used as a three-terminal element or a two-terminal element. The latter can be regarded as a variable resistor because its function in the circuit is to obtain the input voltage (applied voltage) and form a certain relationship with the output voltage, so it is called a potentiometer.
What is voltage divider?
(1) As a voltage divider potentiometer , it is a continuously adjustable resistor. When the rotating handle or sliding handle of the divider is adjusted, the moving contact slides on the resistor. At this time, the output voltage of the potentiometer, which is related to the applied voltage of the potentiometer and the angle or stroke of the movable arm, can be obtained at the output end of the potentiometer.
What is a resistor made of?
It is the most used potentiometer at present. The resistor body is made of a mixture of carbon black, graphite, quartz powder, organic binder, etc., and is coated on a rubber board or a fiberglass board.

So I built this circuit for my Logitech Sub as a control unit and I used a 100K Potentiometer becasue it's what I had in hand, but it is originally 10K. It is way more sensitive than it should be. So my question is if I use a 10K Pot, will it be more or less sensitive to turning the dial? Thanks :)
kelvinhall05
I might be wrong but I think the difference between a 10k and 100k pot is that the 10k has up to 10kΩ of resistance, while the 100k has up to 100kΩ of resistance. I don't think this would change how sensitive the adjustment is as they're both infinitely variable.
vf1000ride
The difference in the sensitivity comes from the ratio of the change in resistance per degree of rotation.
mariushm
Another option would be to add resistors in parallel (two resistors, one between each side pin and the wiper pin)
Grabhanem
It looks like in that circuit they are already sort of doing what @mariushm said, using resistors in both series and parallel to correct the range. Therefore unlike most potentiometer circuits the resistance of the pot does actually matter.
DrDsNo1
The potentiometer is part of voltage divider circuit consisting of r102, r103, r104, r105, and r106 . If you want to use a 100k pot then you have to mutiply the values of the other resistors by 10. This brings the pot back in to proportion with the others.The sensitivity of the circuit will be decreased this way.
What is a high precision potentiometer?
In analog computers, high precision potentiometers are used to scale intermediate results by desired constant factors, or to set initial conditions for a calculation. A motor-driven potentiometer may be used as a function generator, using a non-linear resistance card to supply approximations to trigonometric functions. For example, the shaft rotation might represent an angle, and the voltage division ratio can be made proportional to the cosine of the angle.
What is a potentiometer used for?
The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name. Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment.
What is a multiturn potentiometer?
Some multiturn potentiometers have a linear resistive element with a sliding contact moved by a lead screw ; others have a helical resistive element and a wiper that turns through 10, 20, or more complete revolutions, moving along the helix as it rotates.
What is a linear taper potentiometer?
A linear taper potentiometer ( linear describes the electrical characteristic of the device , not the geometry of the resistive element) has a resistive element of constant cross-section, resulting in a device where the resistance between the contact (wiper) and one end terminal is proportional to the distance between them. Linear taper potentiometers are used when the division ratio of the potentiometer must be proportional to the angle of shaft rotation (or slider position), for example, controls used for adjusting the centering of the display on an analog cathode-ray oscilloscope. Precision potentiometers have an accurate relationship between resistance and slider position.
What is a digipot?
A digital potentiometer (often called digipot) is an electronic component that mimics the functions of analog potentiometers. Through digital input signals, the resistance between two terminals can be adjusted, just as in an analog potentiometer. There are two main functional types: volatile, which lose their set position if power is removed, and are usually designed to initialise at the minimum position, and non-volatile, which retain their set position using a storage mechanism similar to flash memory or EEPROM .
What is an anti-log pot?
There is also an anti-log pot or reverse audio taper which is simply the reverse of a logarith mic potentiometer. It is almost always used in a ganged configuration with a logarithmic potentiometer, for instance, in an audio balance control.
What is a slide pot?
slide pot or slider pot: a potentiometer that is adjusted by sliding the wiper left or right (or up and down, depending on the installation), usually with a finger or thumb. thumb pot or thumbwheel pot: a small rotating potentiometer meant to be adjusted infrequently by means of a small thumbwheel.

Besides the obvious, I am wondering what the difference is between 5K pot and 10K pot. The schematic I'm using has the VR1 listed as 10K. I only had a 5K pot on hand so I used it. It seems to run just fine.
