Question

What is current density ?discuss it.

Answer 1

Answer:

The current density vector is defined as a vector whose magnitude is the electric current per cross-sectional area at a given point in space, its direction being that of the motion of the positive charges at this point. In SI base units, the electric current density is measured in amperes per square metre.

In SI base units: A m−2

Common symbols: j →

Answer 2

Answer:

Current density is the measuse of the density of an electric current. It is defined as a vector whose magnitude is the electric current per cross-sectional area. In SI units, the current density is measure in amperes per sq. m
