Resistor is not a semiconductor device but electronics circuits are immobile without resistors. The reason is that all the components used in the circuit have the same operating voltage. As a result, resistors are used to provide different voltages for different components. A resistor is a passive component, it has no polarity. Different values of resistors are used in circuits based on current and voltage ratings.
