How resistivity is different from resistance |
| Answer» Resistance:\tThe\xa0ratio of the potential difference between the two ends of a conductor to the current flowing through at uniform temperature is called resistance of that conductor.\tThe unit of resistance is ohm (Ω).\tResistance of conductor depends on its length, temperature, cross section area, material of the conductor.\tResistance is related with a particular conductor.Resistivity:\tAt a fixed temperature amount of resistance offered in the flow of current by a conductor having unit length and unit cross section is called its resistivity or specific resistance.\tThe unit of resistivity is ohm-meter (Ω-m).\tresistivity of conductor depends on the material of the conductor and its temperature.\tResistivity is related with the material of the conductor. | |
