Question

In the equation AB = C, A is the current density, C is the
electric field, Then B is
(a) resistivity (b) conductivity
(c) potential difference (d) resistance

Answer 1

Answer:

please mark me as a brain list

Explanation:

We know that J=σE where J=current density, σ= conductivity and E= electric field.

also, resistivity ρ=

σ

1

thus,

σ

J

=E

or Jρ=E

Therefore , B=ρ

Answer 2

Answer:

(a) resistivity

Explanation:

according to ohm's law
