An electric current passes through non-uniform cross-section wire made of homogeneous and isotropic material. If $j_A$ and $j_B$ are the current densities and $E_A$ and $E_B$ ate the electric field intensities at A and ,B respectively, then

• A

  ${\mathrm{j}}_{\mathrm{A}}>{\mathrm{j}}_{\mathrm{B}};{\mathrm{E}}_{\mathrm{A}}>{\mathrm{E}}_{\mathrm{B}}$

• B

  ${\mathrm{j}}_{\mathrm{A}}>{\mathrm{j}}_{\mathrm{B}};{\mathrm{E}}_{\mathrm{A}}<{\mathrm{E}}_{\mathrm{B}}$

• C

  ${\mathrm{j}}_{\mathrm{A}}<{\mathrm{j}}_{\mathrm{B}};{\mathrm{E}}_{\mathrm{A}}>{\mathrm{E}}_{\mathrm{B}}$

• D

  ${\mathrm{j}}_{\mathrm{A}}<{\mathrm{j}}_{\mathrm{B}};{\mathrm{E}}_{\mathrm{A}}<{\mathrm{E}}_{\mathrm{B}}$
