Answer:

Current density is defined as the ratio of current flowing in the conductor to the cross-sectional area of the conductor perpendicular to the direction of current flowing.

Relation between current density J and drift speed vd is given by   J=n e vd

where n is the number density of electrons and e is the electronic charge.

Explanation:
