Question

For 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/​

Answer 1

Answer:

answer is (b) option

Explanation:

because it doesn't follow ohm's law
