Question

Electric field and current density (J) have relation

• A. $E\propto J^{-1}$
• B. $E\propto J$
• C. $E\propto \frac{1}{J^2}$
• D. $E^2\propto \frac{1}{J}$

Answer 1

Answer: (B)

According to the relation
$\sigma E=J$, where $\propto$ is conductivity and is a constant for specific material
$E\propto J$
