What is a variable resistor?

Variable resistors, also known as potentiometers, are electronic components that allow the adjustment of resistance within a circuit. Typically, these resistors allow users to change the resistance value by rotating or sliding a control mechanism. This enables the regulation of current and voltage within a circuit. Variable resistors are widely used in applications such as volume control, brightness adjustment, and feedback regulation. For instance, in audio equipment or lighting systems, users can fine-tune signal strength or device performance according to their desired settings. A typical variable resistor has three terminals: input, output, and the adjustable terminal.

Application of variable resistor

✅ Audio Equipment
Used in speakers and audio systems to adjust volume.
✅ Lighting Systems
Employed to control the brightness of lights in a system.
✅ Adjustment Circuits
Can be used in feedback control systems, such as in motors or sensors.
