Question

what is current density ? write the vector equation connecting current density J with electric field intensity E​

Answer 1

Current Electricity: It is defined as the electric current per unit cross sectional area (area normal to current) to any point in a conductor.

J = I / A

S.I unit is A $m^{-2}$

The vector equation connectivity current density j with electric field intensity E for ohm conductor is as following:

J = o E

Where o is the conductivity.
