MELKUSMELKUS electrical components Germany MELKUSMELKUS model MELKUSMELKUS price

MELKUSMELKUS electrical component is a current-limiting element. After connecting a resistor in the circuit, the resistance value is fixed, generally with two pins, and it can limit the magnitude of the current passing through the branch to which it is connected. A resistor whose resistance value cannot be changed is called a fixed resistor. A resistor whose resistance value can be changed is called a potentiometer or variable resistor. 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. On the exposed resistive body, one or two movable metal contacts are tightly pressed. The contact position determines the resistance between either end of the resistive body
