what is a specific resistance. Give it's resistance.

Explanation:
Specific Resistance is the inherent property of a material. It is defined as the resistance offered by a unit length(say 1cm) and unit cross section area(say 1sq.cm) of that material when a known voltage is applied at its ends. Mathematically, p=Ra/l. p --> Specific resistance.
.
Specific resistance is defined as the resistance offered per unit length and unit cross-sectional area when the known amount of voltage is applied. The mathematical representation is as follows:
ρ=RAL
Where,
⍴: specific resistance
R: resistance
A: cross-sectional area
L: length of the material
Specific resistance is the reciprocal of specific conductance, which is defined as a measure of a material’s ability to conduct electricity. The symbolic representation of specific conductance is . It may also refer to:
Specific electric resistance
Specific airway resistance
Specific resistance due to friction for a mechanism transporting mass.
