R = ¶L÷A
¶=a constant, Resistivity(specific resistance)
L= length of the conductor
A= area of cross section
If the radius of wire is doubled area increases by 4 times R decreases by 4 times
But specific resistance remain same. It is the property of given material

No change in specific resistance as it depends only material and temperature
