ott 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. On the exposed resistive body, one or two movable metal contacts are pressed firmly. The position of the contacts determines the resistance between either end of the resistive body and the contact.
