Question

A steady current flows in a metallic conductor of non-uniform cross-section. Which
of these quantities is constant along the conductor ?

​

Answer 1

Answer:

When a steady current flows in a metallic conductor of non uniform cross-section, the current flowing through the conductor is constant. Current density, electric field, and drift speed are inversely proportional to the area of cross-section. Therefore, they are not constant.

Answer 2

Answer:

a] When a steady current flows in a metallic conductor of non uniform cross-section, the current flowing through the conductor is constant. Current density, electric field, and drift speed are inversely proportional to the area of cross-section. Therefore, they are not constant.
