What Is A Potentiometer and How Does It Work?

A potentiometer is a three-terminal variable resistor that may be manually adjusted. Two terminals are linked to the resistive element, while the third is connected to a wiper, a sliding contact. The resistive element is being moved over by the wiper. The potentiometer can be understood as a divider of variable resistance in its simplest form. The resistive element is analogous to two parallel resistors providing the potentiometer’s total resistance. To adjust the ratio of the first to second resistor’s resistance, simply move the wiper to the desired position. When a reference voltage is provided across the potentiometer’s terminals, the output voltage is proportional to where the wiper is positioned.

When referring to a potentiometer, you may also hear the term “pot,” “potmeter,” or “pots” used. The most common type of potentiometer is the single-turn rotary potmeter. This particular strainer is used for several things, including logarithmic tapering for volume control in audio systems. Potentiometers can be constructed from many materials, including carbon composition, wire wound, cermet, conductive plastic, and metal film.

The potential drop across any part of the wire will be directly proportional to the length of the wire, given that the wire has a uniform cross-sectional area and a uniform current flow across the wire. This is the fundamental idea behind the potentiometer.

What is a Digital Potentiometer?

Digital potentiometers are three-terminal devices with two fixed-end terminals and a third wiper terminal for adjusting the output voltage.

Calibration of a system, tweaking an offset voltage, fine-tuning a filter, adjusting the brightness of a display, and adjusting the volume of an audio system are all possible with the help of a digital potentiometer.

However, mechanical potentiometers have several major limitations that make them inappropriate for uses that necessitate a high degree of precision. Mechanical potentiometers have several limitations that make them less than ideal for many applications, such as their bulkiness, vulnerability to wiper contamination, mechanical wear, resistance drift, susceptibility to vibration and humidity, and so on. Despite these drawbacks, digital potentiometers rapidly replace analog versions due to their superior accuracy in various practical contexts.

What is a Potentiometer Sensitivity?

By definition, a potentiometer’s sensitivity is its ability to pick up on extremely minute voltage fluctuations. If we lengthen the potentiometer while keeping the driver voltage constant, we will increase the resistance per unit voltage. This increases the potentiometer’s responsiveness. To put it another way, the potentiometer’s sensitivity is directly proportional to the length of the resistance. Like before, reducing the drive voltage for a given length of potentiometer resistance reduces the voltage per unit length of the resistance. This results in a further increase in the potentiometer’s sensitivity. This means that the potentiometer’s sensitivity drops as the driving voltage rises.

What is a Potentiometer Driver Cell

A potentiometer can measure voltage by comparing the measured value to the voltage that is present across the resistance of the device. For the potentiometer to function, the circuit containing it needs to have a source voltage connected across it. The cell that supplies the source voltage utilized to operate the dial of the potentiometer is referred to as the “driving cell,” and this word is used to characterize the cell. The driver cell will then use the potentiometer’s resistance to supply the current to the load.

The full-scale voltage of the device can be calculated by multiplying the current being measured by the resistance of the potentiometer. One can adjust the sensitivity of the potentiometer by adjusting the voltage. The majority of the time, this is accomplished by making adjustments to the current that is flowing through the resistance. By using a rheostat wired in series with the driver cell, one can exert some degree of control over the amount of current passing through the resistance. To obtain a correct reading, the voltage of the driver cell needs to be higher than the value that is being measured.
