Difference between resistor and resistivity |
| Answer» A\xa0resistor\xa0is an electric component with a predetermined electrical\xa0resistance, like 1 ohm, 10 ohms 100 ohms 10000 ohms etc.The resistivity of a material is the resistance of a wire of that material of unit length and unit cross-sectional area.\xa0The unit for resistivity is the ohm-metre.\xa0The resistivity of a material depends on its nature and the temperature of the conductor, but not on its shape and size.\xa0A good conductor has less resistivity, whereas a bad conductor or insulator has high resistivity. The resistivity of semi-conductors lies between that of conductors and insulators.\xa0 | |
