Question

Express Ohm's law in terms of current density, electrical resistivity and
intensity of electric field.​

Answer 1

Answer:

Electric fields cause charges to move. ...

For an amazingly wide range of materials, an empirical rule called Ohm's law gives the following relation between current density and applied electric field: J = σ E .

In other words, the current density is directly proportional to the electric field.

please mark me as brainly......
