![]() Usually has a shaft with a knob and is designed for routine use, for example a Pot is designed to be used on the circuit board to make adjustments in theĬircuit, which once made are not performed routinely. Position of the wiper when turned fully clock-wise is often denoted on the pot Into two resistors of values xR and (1− x) R. Include the adjustability in the parameter x, which divides R Resistors with the constraint that their series resistance is constant. For the purpose ofĪnalyzing a circuit containing a potentiometer, we include each of these The wiper contactĮffectively divides the resistor into two resistors. Position from one end of the resistor to the other. The wiper position is controlled by a knob that adjusts the wiper Potentiometer is a resistor with a third contact (arrow), which is internallyĬonnected to a wiper (sliding contact) that slides along the resistance Measure resistances and voltages with your DMM. One 1 K trim pot, three resistors (1 K, 3.3 K, and 6.8 K), power supply, DMM,Īn adjustment tool, a solderless bread board, cables, and wire. To understand the characteristics of resistors, potentiometers (pots), Different voltage divider circuits and explore their behavior. ![]()
