Dear Snishant

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)
