Question

Difference between resistance and specific resistance.

Answer 1

Resistance

The ratio 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.
The unit of resistance is ohm (Ω).
Resistance of conductor depends on its length, temperature, cross section area, material of the conductor.
Resistance is related with a particular conductor.





Specific resistance

At 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 specific resistance.
The unit of specific resistance is ohm-meter (Ω-m).
Specific resistivity of conductor depends on the material of the conductor and its temperature.
Specific resistance related with the material of the conductor
