Question

What is Current Density ? I=rA (amp/m2)

Answer 1

Hii mate!!

Here's your answer .

Current density can be defined as amount of current flowing per unit area.

Symbol of current density(J)

J=I/A

SI Unit -:Ampere/metre2

Hope it helps you.

Answer 2

In electromagnetism, current thickness is the electric current per unit territory of cross area. It is characterized as a vector whose extent is the electric current per cross-sectional territory at a given point in space.

In SI units, the electric current thickness is measured in ampere per square meter.

The ampere per meter squared, symbolized A/m 2 , is the International Unit of electric current density . A current density of 1 A/m 2 represents one ampere of electric current flowing through a material with a cross-sectional area of one square meter.
