NEET Physics Ohm's Law MCQ Question with Solution

What is the relationship between current density (j) and electric field (E) as stated in Ohm's Law?

A

j = sE

B

j = rE

C

j = E/s

D

j = E/r

Correct Answer

Option A

Detailed Explanation

Ohm's Law can be represented by the equation j = sE, where s is the conductivity defined as 1/r. This indicates that the current density is directly proportional to the electric field.
