A electric current passes through non uniform cross-section wire made of homogeneous and isotropic material. If the `j_(A)` and `J_(B)` be the current densities and `E_(A)` and `E_(B)` be the electric field intensities at `A` and `B` respectively, then

A

`j_(A)gtj_(B),E_(A)gtE_(B)`

B

`j_(A)gtj_(B),E_(A)ltE_(B)`

C

`j_(A)ltj_(B),E_(A)gtE_(B)`

D

`j_(A)ltj_(B),E_(A)ltE_(B)`
