Resistors are simple devices but they produce many different effects in a circuit. A resistor of nearly pure carbon may be 1 ohm, but when non-conducting "impurities" are added, the same-size resistor may be 100 ohms, 1,000 ohms or 1 million ohms. Circuits use values of less than 1 ohm to more than 22 million ohms. ................
