Dimension of specific resistance ρ is ML3T−1Q−2
Explanation:
The formula relating specific resistance ρ of a conductor to its resistance r is
r=ρlA, where A is area of cross-section.of conductor and l is its length
i.e. ρ=Arl
As dimension of r are ML2T−1Q−2
Therefore dimension of ρ is ML2T−1Q−2×L2L
= ML3T−1Q−2
