Question

Q6. For a fixed conductor at a fixed
temperature, which of the following
is not the mathematical statement of
Ohm's law?(V = potential difference,
| = current, E = electric field, J =
current density, p = resistivity, o =
conductivity, I = length of conductor,
A = area of conductor)​

Answer 1

Answer:

A.because voltage is directly proportional to current and resistance is inversely proportional to current .

D. R=p l/A we know by the relation that the resistance of conductor is inversely proportional to the area of cross section.
