RSM572-2M electrical component is a current-limiting element. 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. A resistor whose resistance cannot be changed is called a fixed resistor. A resistor whose resistance can be varied is called a potentiometer or variable resistor. An ideal resistor is linear, meaning the instantaneous current through the resistor is directly proportional to the applied instantaneous voltage. Variable resistors are used for voltage division. On the exposed resistive body, one or two movable metal contacts are pressed firmly. The contact position determines the resistance between either end of the resistive body and the contact.
