Kriz electrical components Germany Kriz model Kriz price

Kriz electrical components are current-limiting elements. When a resistor is connected in a circuit, its resistance is fixed, typically with two pins, and it limits the current flowing through the branch to which it is connected. Resistors with unchangeable resistance are called fixed resistors. Those with variable resistance are called potentiometers or variable resistors. An ideal resistor is linear, meaning the instantaneous current through the resistor is proportional to the applied instantaneous voltage. Variable resistors used for voltage division have one or two movable metal contacts pressed tightly against the exposed resistive body. The position of the contact determines the resistance between either end of the resistive body and the contact.
