Resistors, Trimmers, TrimPot. Potentiometers also known as POT are nothing but variable resistors. They can provide a variable resistance by simply varying the knob on top of its head. It can be classified based on two main parameters. Potentiometer comes in various structure and designs. Some have rotatory shaft, some come in compact size known as preset w resistor or trimmer pot which have the arrangement to adjust the resistance at a desired value.
