The american style resistor is drawn as a zigzag resistor while the european style resistor is drawn as a rectangular resistor. Various preset potentiometers are shown in the right of the photo. It is like the resistor. Since it is not marked (as one would hope) on the schematic, you may hope what see is the minimum position is pin 1 (CCW). 10 ohm, 100 ohm, 470 ohm, 10k ohm, 22k ohm, etc. Ask Question Asked 2 years, 9 months ago. The rated resistance of the potentiometer can always be measured between the outer two pins – e.g. The centre pin or "wiper" moves along the resistive material between the two outer pins. Potentiometer Schematic Symbol, Drawing, And Photograph. Many thanks to all who have donated. The resistance between an outer pin and the wiper will change as the shaft of the potentiometer is rotated. we call the middle pin the wiper. Potentiometer (Variable Resistor) A potentiometer, also known as a variable resistor, has a resistance value determined by the position of an internal wiper (shown by the arrow). A potentiometer is a resistor that has a mechanical shaft or screw that can be turned to change its resistance. The symbol on the right belongs to a “trimpot,” which is a potentiometer adjustable only by a screwdriver, intended for non-routine adjustments.
