What is the difference btween resistance and resistivity and resistor |
| Answer» \tResistanceResistivityResistance is the physical property of a substance because of which it opposes the flow of current i.e. electrons.Resistivity is the physical property of a particular substance which is having particular dimensions.Resistance is directly proportional to the length and temperature while it is inversely proportional to the cross-sectional area of the material.Resistivity is only proportional to the nature and temperature of the particular material.The SI unit of resistance is OhmsThe SI unit of resistivity is Ohms-meter.The property of resistance is used in several places like heaters, fuses, sensors, etc.Electrical resistivity measurement is used as a quality control test for calcareous soil.\t\xa0 | |
