Question

Define specific resistance or resisrivity of a conductor. What is its unit ?

Resistivity of copper is 1.78×10^-6 ohm.com what do you mean by this statement ?​

Answer 1

Answer:

Explanation:

1. 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. ... specific resistance or resistivity is the resistance of a material

Answer 2

Answer:

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.

SI unit of specific resistance is ohm meter (Ωm)
