Resistance= resistivity×length/area
R = rL/A
where
R = resistance
r= resistivity
L = length of wire
A = area of cross section of wire
R = rL/A
where
R = resistance
r= resistivity
L = length of wire
A = area of cross section of wire

resistivity = 1/ resistance
R = p L/A
where , R = resistance
p = resistivity
L = length of conductor
A = area of cross section of the conductor.
hope this helps u......

TPS:
thats wrong. resistivity is not equal to 1 by resistance
