Q. $ML^{3}T^{- 1}Q^{- 2}$ is dimensions of
A) Resistivity
B) Conductivity
C) Resistance
D) None of these
Explanation
Resistivity $\lbrack\rho\rbrack = \frac{\lbrack R\rbrack.\lbrack A\rbrack}{\lbrack I\rbrack}$ where $\lbrack R\rbrack = \left\lbrack ML^{2}T^{- 1}Q^{- 2} \right\rbrack$ $\therefore\lbrack\rho\rbrack = \left\lbrack ML^{3}T^{- 1}Q^{- 2} \right\rbrack$
