The correct interpretation of Ohm's law is: (Here, $\vec{J}$ is current density, '$\sigma$' is conductivity, $\vec{E}$ is electric field and '$\rho$' is resistivity.)
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → $\vec{E}=\vec{J}_\rho$
In terms of resistivity (ρ), which is the inverse of conductivity $ρ=1/σ$, the law can be
$\vec J=σ\vec E⇔\vec E=\vec Jρ$
