Question

What is specific resistance?

Answer 1

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

Where,

p is Specific resistance/ resistivity

R is Resistance

A is cross sectional area of the material

L is length of the material
