Information
Potentiometer controlled by a thumbwheel. The model consists of two variable resistors, to total resistance of which equal the parameter maxRes. When the thumbhweel is turned all the way to the left, almost all of the total resistance will be present between the right resistor and the wiper pin. This model represents a potentiometer where the wiper pin is slided along a material whose resistance is lineraly proportional to its length. By turning the thumbwheel to the right, the distance between the positive pin and the wiper becomes larger and the resistance between them increases lineraly.
