Potentiometers for circuit board components
A potentiometer is basically an advanced form of a simple resistor. Simple resistors have a fixed resistance value. However, the resistance value of the potentiometer can be changed as needed. There are many types of potentiometers, but the most common are linear and rotary types. You can change the resistance of the linear potentiometer by dragging the linear slider. On a rotary potentiometer, you can turn the knob to change the resistance. The resistance changes as the slider moves over the semicircular base resistance.We use rotary potentiometers a lot in everyday applications, the most common one being in the circular faders of music players and similar audio equipment, and they work by controlling the amount of current delivered to the amplifier. When potentiometers are designed for complex equipment, fine-tuning is required to change their performance.
