Potentiometer Fundamentals

What is a potentiometer and how does it work?

The potentiometer, commonly referred to as a potmeter or a pot, is a three-terminal mechanically operated rotary analogue device which can be found and used in a large variety of electrical and electronic circuits. They are passive devices, meaning they do not require a power supply or additional circuitry in order to perform their basic linear or rotary position function.

Today, potentiometers are much smaller and much more accurate than those early large and bulky variable resistances, and as with most electronic components, there are many different types and names ranging from variable resistor, preset, trimmer, rheostat and of course variable potentiometer. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat.

In addition, a potentiometer is a type of position sensor. They are used to measure displacement in any direction. Linear potentiometers linearly measure displacement and rotary potentiometers measure rotational displacement.

What are different types of potentiometers?

potentiometer and rheostat symbols

Potentiometers have many types. A basic potentiometer is a three-terminal resistor with a sliding or rotating contact, they are available in a variety of different mechanical variations allowing for easy adjustment to control a voltage, current, or the biasing and gain control of a circuit to obtain a zero condition. There are two main types of potentiometer, linear potentiometers and rotary potentiometers. Membrane Potentiometers are another type of potentiometer they are often referred to as “soft pots” and can be either linear or rotary. The most common potentiometers are rotary potentiometers, linear potentiometers, digital potentiometers, slider potentiometer, rheostat, preset or trimmer potentiometers. This page is introducing Potentiometer Types completely as an electronic tutorial.

Potentiometer Applications

What is application of potentiometer?

Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment and adjust the level of analog signals (for example volume controls on audio equipment), or as control inputs for electronic circuits. They are rarely used to directly control significant amounts of power (more than a watt or so). So that it is hard to list all of their functions here. Potentiometers are used to accurately measure voltage and help achieve a variable voltage from a fixed-voltage source. For example, The potentiometer essentially functions as a variable voltage divider used for measuring electric potential (voltage). If you want to get to know more info about Potentiometer Application, visiting the following page deeply.

↪️Audio Control
Low-power potentiometers, both slide and rotary, are used to control audio equipment, changing loudness, frequency attenuation, and other characteristics of audio signals.
↪️Television
Potentiometers were formerly used to control picture brightness, contrast, and color response. 
↪️Motion Control
Potentiometers can be used as position feedback devices in order to create closed-loop control, such as in a servomechanism. 
↪️Transducers
Potentiometers are also very widely used as a part of displacement transducers because of the simplicity of construction and because they can give a large output signal.
↪️Computation
In analog computers, high precision potentiometers are used to scale intermediate results by desired constant factors, or to set initial conditions for a calculation.
