A) \[[M{{L}^{-3}}{{T}^{3}}{{I}^{2}}]\]
B) \[[{{M}^{-1}}{{L}^{3}}{{T}^{2}}{{I}^{3}}]\]
C) \[[{{M}^{-1}}{{L}^{-2}}{{T}^{3}}{{I}^{2}}]\]
D) \[[{{M}^{-1}}{{L}^{-3}}{{T}^{3}}I]\]
Correct Answer: C
Solution :
Conductivity \[=\frac{Length}{~Resistance\times Area}\] \[=\frac{[L]}{[M{{L}^{2}}{{T}^{-3}}{{I}^{-2}}]\,\,[{{L}^{2}}]}\] \[=[{{M}^{-1}}{{L}^{-3}}{{T}^{3}}{{I}^{2}}]\]
