How is electrical conductance of a conductor related with length and area of cross section of the conductor ?

Options

A. `G = I.a.k^(-1)`
B. `G = k.I.a^(-1)`
C. `G = k.a.I^(-1)`
D. `G = k.I.a^(-2)`

Answer

C

Explanation

Electric conductance is given by ,
`G = k * a * I^(-1)`
where , k (kappa) is specific conductance
