Explanation:

hloFor a fixed conductor at a fixed temperature, which of the following is not the mathematical statement of Ohm’s law?( V = potential difference, I = current, E = electric field, J = current density, = resistivity, = conductivity, l = length of conductor, A = area of conductor) *

(a) V ∝ I

(b) E = J ρ

(c) J = σ E

(d) R = ρ l/A
