The conductivity of a material with current density 1 unit and electri...
Answer: d
Explanation: The current density is given by, J = σE. To find conductivity, σ = J/E = 1/200 X 10-6 = 5000.

The conductivity of a material is defined as the ratio of current density to electric field. Therefore,

conductivity = current density / electric field
conductivity = 1 unit / 200 V/m
conductivity = 0.005 S/m

The units of conductivity are Siemens per meter (S/m).
