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

Electrical condictivity
`sigma = (J)/(E ) = [(l//A)/(F//q)]`
`= [(l//A)/(F//it)]=[(l^(2)t)/(FA)]`
`=[(A^(2)t)/((MLT^(-2))(L^(2)))]`
`= [M^(-1) L^(-3) T^(3) A^(2)]`.
