If you want to know the difference betweenResistance and Resistivity the eaplanation is the following
Let us start with equation relating Resistance(R) and relitivity(ρ).
R= ρ ( L/A) Where A= Crossecion area of the wire, L= length.
R= Total resistane cauised by the wire
ρ = Resistane fo a wire with One unit length and one unit crossectionl area. (I .e if L=1, A=1 ==> R=ρ)
