Question

What is Current Density ?​

Answer 1

Answer:

In electromagnetism, current density is the amount of charge per unit time that flows through a unit area of a chosen cross section. ... In SI base units, the electric current density is measured in amperes per square metre.

Answer 2

$\huge{\bold{ \underline{ \red{ \sf{Answer}}}}}$

${\underline{\sf{Current Density}}}$

Current density at any point in conductor is the ratio of current to area vector perpendicular to current.

Current Density is always indicated by J

=> [J=I/A]

=> Vector Quantity

=>Direction is always in the direction of current

=>Unit is A/m^2
