From ohm's law Electric field propto current density

Q. A resistance of frustum shape is shown in figure. If a current $i$ passes through the resistance, the electric field at $A$ and $B$ are related as

$E_{A} > E_{B}$

$E_{B} > E_{A}$

$E_{A} = E_{B}$

there is no relation

From ohm's law
Electric field $\propto$ current density

Q. A resistance of frustum shape is shown in figure. If a current i passes through the resistance, the electric field at A and B are related as

EA​>EB​

EB​>EA​

EA​=EB​
