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

How is current density related to electric field?

What is current density? Write the vector equation connecting current density J with electric field intensity E for an ohmic conductor.

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?

Electric current density is ..... .
