Question

Derive expression for specific resistance at material?

Answer 1

Explanation:

measure of the potential electrical resistance of a conductive material. It is determined experimentally using the equation ρ = RA/l, where R is the measured resistance of some length of the material, A is its cross-sectional area (which must be uniform), and l is its length. It is measured in ohm-meters.Specific Resistance is the inherent property of a material… It is defined as “ the resistance offered per unit length and unit cross sectional area of that material when a known quantity of voltage is applied at its end”… Mathematically specific resistance is given by, p=(RA)/L.
