Potentiometers, often referred to as "pots," are essential components in electronic devices, offering precise control over voltage and current. These versatile components are widely used in applications ranging from volume knobs in audio equipment to advanced robotics. In this blog, we explore the mechanics, types, applications, and advantages of potentiometers , as well as how to choose the right one for your project. What Is a Potentiometer? A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. It is a type of variable resistor commonly used to control electrical parameters like voltage and current in circuits. Key Components of a Potentiometer: Resistive Element : The material that provides resistance, usually carbon, cermet, or wire-wound material. Wiper : The movable contact that slides along the resistive element to adjust the resistance. Terminals : Three connections—two for the resistive track ends an...
