Potentiometer
Potentiometers are variable resistors. Potentiometers are resistors where the resistance can be changed using a knob or a slider. Potentiometers are used to control many things, including how bright or dim the lights in your house are and the volume controls on your television.[1] Some are used in voltage dividers.
The idea of a device that could be used to control the amount of electricity going to a component was thought by many people, but the carbon potentiometer we commonly use today was invented by Thomas Edison in 1872 at the age of 25. He called this device a "coiled resistance wire rheostat". His patent for this device was issued in 1872. Carbon resistors, as said above, are the most commonly used resistors today. They are used in radios to control the volume, in televisions to control picture brightness, contrast, and color response.[2][3][4]
