Potentiometers, also known as variable resistors or pots, are crucial electronic components used for controlling the flow of electric current. They provide a means to adjust the resistance in a circuit, allowing for precise control over various parameters such as volume, brightness, speed, and more.
Potentiometers are widely used in audio equipment, lighting systems, motor control circuits, and many other applications where fine-tuning is required. By turning the knob or slider on a potentiometer, users can modify the resistance and, consequently, the output or behavior of the associated circuit.
