A potentiometer, informally a pot, is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat.
These potentiometers require manual adjustments by the user. Most of the time, knobs are used to assist with the manual dialing to manage the value of the pot. Zero Ohm currently provides two color variations: White and Red knobs. Available in Dubai, UAE, Oman, and Qatar!
