Question

On what factors the resistancy of a conductor depends give its mathematical expression?

Answer 1

Explanation:

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.
