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

Options

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

Answer

B

Explanation

`D= [M^(-1)L^(-3)T^(+3)A^(2)]`
`sigma = (1)/(p)=(l)/(RA)=(Il)/(VA)=(I^(2)l)/((VI)A)= ([A^2][L])/([ML^(2)T^(-3)][L^2])`
`=[M^(-1)L^(-3)T^(3)I^(2)]`
