Demke electrical components Germany Demke model Demke price

Demke electrical components are resistive elements with three terminals, whose resistance can be adjusted according to a specific variation law. A potentiometer typically consists of a resistive element and a movable wiper. When the wiper moves along the resistive element, a resistance value or voltage related to the displacement is obtained at the output terminal. Potentiometers can be used as three-terminal components or as two-terminal components. The latter can be regarded as a variable resistor; since its role in the circuit is to obtain an output voltage that has a certain relationship with the input voltage (applied voltage), it is called a potentiometer. A potentiometer is a type of variable resistor.
