FAQs
What is a potentiometer and how does it work?
A potentiometer is a type of variable resistor that allows for the adjustment of electrical resistance in a circuit. It works by using a sliding contact to tap into a resistive material, such as carbon or wire, and create a variable voltage divider. The potentiometer has three terminals: two fixed terminals at either end of the resistive material and a third terminal connected to the sliding contact. By adjusting the position of the sliding contact, the user can change the ratio of resistance between the two fixed terminals, effectively controlling the voltage output.
The working principle of a potentiometer is based on the concept of voltage division, where the voltage output is proportional to the ratio of resistance between the two fixed terminals. When the sliding contact is moved, the resistance between the fixed terminals changes, resulting in a corresponding change in the voltage output. This makes potentiometers ideal for applications such as volume control, tone control, and sensor calibration. With their high precision and reliability, potentiometers are widely used in various industries, including audio equipment, medical devices, and industrial automation.
