Question

On what factor the resistance of conductor depends give its mathematical expression give the SI unit of resistivity​

Answer 1

Answer:

the resistance depends upon resistivity of the material, length, temperature, and area of cross-section. Mathematically, R=pl/A where p is the resistivity,l is the length and A is area of cross section. from above, p = RA/l = ohm*m2/m = ohm-metre
