The ratio of current density and electric field is called (A) resistivity (B) conductivity (C) Drift velocity (D) Mobility

The ratio of magnitude of current density and magnitude of electric field inside the conductor is

Give relation between drift velocity and electric field.

a. A steady current flows in a metallic conductor of non - uniform cross section. State which of the quantities i.e., current density, electric field, and drift velocity, current density, electric field, and drift velcoity remain constant? b. A steady current passes through a cylindrical conductor. Is there an electorn field inside the conductor?

In the equation AB = C, A is the current density, C is the electric field, Then B is
