The physical quantity having the dimensions `[M^(-1)L^(-3)T^(3)A^(2)]` is

Options

A. resistance
B. resistivity
C. electrical conductivity
D. electromotive force

Answer

C

Explanation

Resistivity, `rho=-(m)/("ne"^(2)tau)`
`=(M)/(L^(-3)(AT)^(2)T)=ML^(3)A^(-2)T^(-3)`.
Conductivity, `sigma =(1)/(rho)=(1)/(ML^(3)A^(-2)T^(-3))=M^(-1)L^(-3)A^(2)T^(3)`.
