The Potentiometer: What Is It?

A variable resistor that can be adjusted manually and has three terminals is called a potentiometer. Two terminals are linked to the opposite ends of a resistive element, while the third terminal is attached to a sliding contact termed a wiper. The wiper is moving over the resistive element. The potentiometer can be thought of as a variable resistance divider in its most basic form. The resistive element can be thought of as two resistors connected in series, which together make up the total resistance of the potentiometer. The position of the wiper controls the proportion of the first resistor’s resistance to that of the second resistor. The output voltage of the potentiometer is determined by the position of the wiper when a reference voltage is applied across the end terminals of the potentiometer.

Potentiometers are also sometimes referred to by the names potmeters and pots. The single-turn rotary potmeter is the most typical device known as a potentiometer. This pot form is frequently utilized in various applications, one of which is regulating audio volume using a logarithmic taper. Various materials can be used to make potentiometers, such as carbon composition, wire wound, cermet, conductive plastic, or metal film.

The Functioning Mechanism of a Potentiometer

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.

Digital Potentiometers

Devices known as digital potentiometers have three terminals: two end terminals fixed in place and a third terminal known as the wiper terminal used to adjust the output voltage.

Digital potentiometers can be used for various purposes, including system calibration, offset voltage adjustment, filter tuning, screen brightness control, and sound volume control.

On the other hand, mechanical potentiometers have several significant drawbacks, which render them unsuitable for applications requiring high levels of precision. Some of the most significant drawbacks of using a mechanical potentiometer include its size, potential for wiper contamination, mechanical wear, resistance drift, sensitivity to vibration and humidity, and so on. As a result of these disadvantages, digital potentiometers are becoming increasingly prevalent in application settings because of their improved precision.

Potentiometer Driver Cell

The potentiometer determines the voltage by comparing the measured voltage to the voltage that is present across the resistance of the potentiometer. Therefore, a source voltage must be connected across the potentiometer circuit for the potentiometer to function properly. This cell, which supplies the source voltage needed to drive the potentiometer, is called the driver cell. The current is sent to the load by the driver cell via the resistance of the potentiometer. The full-scale voltage of the device is determined by the product of this current and the resistance of the potentiometer. One can vary the sensitivity of the potentiometer by adjusting the voltage in this way. Adjusting the amount of current that flows through the resistance is the typical method used to do this. A rheostat connected in series with the driver cell can adjust the current flow through the resistance. Remember that the voltage of the driver cell needs to be higher than the voltage being measured for the measurement to be accurate.

Potentiometer Sensitivity

As the name suggests, a potentiometer’s sensitivity refers to how accurately it can detect even the smallest changes in voltage. By increasing the length of the potentiometer, we can achieve a greater resistance per unit voltage while maintaining the same driving voltage. As a result, the potentiometer’s sensitivity improves. We may therefore state that the potentiometer’s sensitivity is proportional to the resistance’s length. As before, lowering the drive voltage for a certain length of potentiometer resistance also lowers the voltage per unit length of the resistance. As a result, the potentiometer’s sensitivity is raised once more. Because of this, a higher driver voltage results in a lower potentiometer sensitivity.
