What is the function of a potentiometer?
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 does 10K potentiometer mean?
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.

What value potentiometer do I need?
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.
Do potentiometer Values Matter?
So the overall value of the pot doesn't really matter. Where the value does come into play is how power it dissipates. Power = Current x Voltage, or P=IV.

How many feet does a potentiometer have?
In fact, the potentiometer is a resistor that can adjust resistance value according to its function. It has three feet and one foot at each end. The resistance value corresponding to these two feet is fixed, called the nominal resistance value. The middle foot can slide on resistance, called slider.
What are the characteristics of a potentiometer?
In addition to the nominal resistance and rated power, the main parameters of the potentiometer also have a resistance change characteristic, which refers to the relationship between the resistance value and the rotation angle or sliding stroke of the boom. Common potentiometer resistance changes are linear (X-type), exponential (Z-type), and logarithmic (D-type). The curve of the three types of potentiometer resistance as a function of the angle of rotation of the movable contact is shown in Figure 1. The ordinate in the figure represents the actual value of the resistance at a certain angle and the percentage of the total resistance of the potentiometer. The abscissa is the percentage of the rotation angle and the maximum rotation angle.
How long does a potentiometer last?
Generally, the mechanical length of a synthetic carbon film potentiometer can be as high as 200,000 weeks, while the mechanical test of a glass glaze potentiometer is only 100-200 weeks. When using a potentiometer, the potentiometer with different mechanical life parameters should be selected according to the different requirements of the circuit for wear resistance.
Why is the accuracy of a potentiometer low?
Because of temperature changes, the abrasion and fouling between the slider and the variable resistor will cause resistance changes, which will affect the accuracy of the potentiometer, and cause the accuracy of the potentiometer to be too low.
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.
What is the resistance change of a X-type potentiometer?
The resistance change of the X-type potentiometer is linear with the rotation angle. That is, the distribution of the conductive material on the resistor body is uniform, so the resistance per unit length is equal. It is suitable for some applications that require uniform adjustments, such as voltage dividers, bias current adjustment and other circuits. When the Z-type potentiometer starts to rotate, the resistance value changes little, and when the rotation angle approaches one end of the maximum rotation angle, the resistance value changes more obviously.
