Question

what is specific resistivity

Answer 1

$\textbf{DEAR FRIEND}$

The electrical resistance of an electrical conductor is a measure of the difficulty to pass an electric current through that conductor. The inverse quantity is electrical conductance, and is the ease with which an electric current passes.




HOPE THIS HELPS

Answer 2

The specific resistance or resistivity of a conductor is the resistance of a wire of that material of unit length and unit area of cross-section. 

The symbol for resistance is ρ (rho).

Resistivity (ρ) = Resistance * area/length

The S.I unit of specific resistance is ohm * meter

Hope this helps you.
