What are Potentiometer Knobs?
A potentiometer knob is an accessory that is used to control different output levels on a potentiometer. These knobs sit on top of the potentiometer to enable the increasing or decreasing of values on an electrical device, such as a volume control knob on a stereo.
Now to really understand potentiometer knobs, we need to know what a Potentiometer is. To put it simply, a potentiometer is a type of resistor that can be manually controlled to change its value of resistance. Thus, increasing or decreasing the output. A potentiometer generally works by adjusting the value of voltage with the help of (you guessed it) potentiometer knobs.
What are the Uses of Potentiometer Knobs?
The uses of potentiometer knobs are almost identical to the uses of a potentiometer. After all, the knobs are practically a part of the potentiometer. Here are some of the uses of potentiometer knobs.
Whenever we think about the usage of a potentiometer knob, immediately a volume dial pops up in the head that we can manually turn to control the volume on a stereo or a deck. You might have observed these in your car. Besides volume control, potentiometer knobs are also used to adjust the frequency (for tuning radio channels), control bass and treble, and other audio characteristics.
Potentiometers were widely used in old television sets to control picture brightness, contrast, and color response. These were also used for frequency modulation to catch signals from a satellite.
Potentiometers are also used to control lighting situations, especially at studios where different levels of lighting are required to get the best possible shoots. They are also used to control the brightness of lamps to turn up the brightness for desk work or turn down the lighting for bedtime book reading.
