Question

Resistance is directly proportional to Resistivity.? how explain

Answer 1

yes it is true that resistance is directly proportional to resistivity but provided anything out of length and area has to be constant in that case for example if you consider two wires nichrome and copper of same length means length we have kept as constant even if you will take the area of cross section as same and then you will see the resistance it will be different in both cases
this is due to the fact that both of the wires have different values of resistivity nichrome wire has more resistivity than copper hence resistance of nichrome wire is more than that of copper
