Final answer:
The correct relationship between electric intensity (E), current density (j), and specific resistance or resistivity (ρ) is j = E/ρ, which follows from Ohm's Law. None of the given options (A, B, C, D) correctly express this relationship. If we correct option k to ρ, the relationship should be j = E/ρ.
Step-by-step explanation:
The relation among electric intensity E, current density j, and specific resistance which is also known as resistivity ρ, is given by the equation j = E/ρ. This relationship can be derived from Ohm's Law which states that current is directly proportional to voltage and inversely proportional to resistance. The electric field (E) in a material with resistivity (ρ) will produce a current density (j), and they are related such that the current density is directly proportional to the electric field and inversely proportional to the resistivity.
Given the options:
A. E=jlk
B. E=jk
C. E=klj
D. k=jE
Option B is incorrect because it does not take into account resistivity. Option C is incorrect because the letters are out of order and resistivity should be represented as ρ not k. Option D suggests that resistivity is the product of current density and electric field, which is not true. Therefore, the correct option is not listed, but if we replace k with ρ, the correct relationship would be
j = E/ρ
, which is not directly given in any of the options provided.
