Potentiometers, also known as pots or variable resistors, are essential electronic components that provide adjustable resistance in a circuit. Their versatile functionality enables them to serve as voltage dividers, volume controls, and sensors, among other applications. Understanding how to wire a potentiometer correctly is crucial for harnessing its full potential and ensuring optimal performance in various electronic systems.
Before delving into the wiring process, it’s important to familiarize yourself with the potentiometer’s terminals. Typically, potentiometers have three terminals labeled as Common (C), Output (O), and Ground (G). The Common terminal is connected to one end of the resistive element, the Output terminal is connected to a wiper that slides along the resistive element, and the Ground terminal is connected to the other end of the resistive element. Understanding the terminal designations is essential for establishing the desired circuit configuration.
The specific wiring configuration of a potentiometer depends on its intended application. For instance, to use a potentiometer as a voltage divider, the Common terminal is connected to the positive voltage source, the Output terminal is connected to the load, and the Ground terminal is connected to the negative voltage source. Alternatively, to use a potentiometer as a volume control, the Common terminal is connected to the output of the audio source, the Output terminal is connected to the input of the amplifier, and the Ground terminal is connected to the ground reference of the system. By adjusting the position of the wiper, the resistance between the Output and Ground terminals changes, allowing for precise control over the output voltage or volume level.
Potentiometer How To Wire
A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. It is used to control the amount of current flowing through a circuit. Potentiometers are commonly used in audio and lighting applications, as well as in electronic circuits where a variable resistance is needed.
To wire a potentiometer, you will need to connect the three terminals to the appropriate points in the circuit. The following diagram shows how to wire a potentiometer in a voltage divider circuit:

In this diagram, the potentiometer is connected between the power supply and the load. The sliding contact of the potentiometer is connected to the input of the load. As the sliding contact is moved, the resistance between the sliding contact and the power supply will change, which will in turn change the voltage at the input of the load.

What is the difference between a potentiometer and a rheostat?
A potentiometer is a three-terminal resistor with a sliding or rotating contact, while a rheostat is a two-terminal resistor with a sliding or rotating contact. Potentiometers are used to control the amount of current flowing through a circuit, while rheostats are used to control the resistance of a circuit.
How do I choose the right potentiometer for my application?
When choosing a potentiometer, you need to consider the following factors:
- The resistance range of the potentiometer
- The power rating of the potentiometer
- The type of potentiometer (linear or logarithmic)
- The size of the potentiometer
