What is a Potentiometer Circuit? A potentiometer circuit is an electrical circuit that utilizes a potentiometer, a three-terminal variable resistor, to control the voltage or current in the circuit. The potentiometer acts as a voltage divider, allowing users to adjust the output voltage by varying the resistance between the wiper (the moving contact) and the fixed resistive element. Components of a Potentiometer Circuit A typical potentiometer circuit consists of the following components: Potentiometer: The main Read more…

Understanding Potentiometers Before we delve into the wiring process, let’s take a moment to understand what potentiometers are and how they work. What is a Potentiometer? A potentiometer, often referred to as a “pot,” is a three-terminal variable resistor that allows you to adjust resistance by rotating a shaft or sliding a wiper. It consists of a resistive element and a wiper that moves along the element, dividing the total resistance into two parts. Types Read more…
