Question

Name the physical quantity whose s.i unit is ampere metre squre

Answer 1

Electric Current Density is the physical unit whose SI unit is ampere per metre square.

Answer 2

The SI unit of electric current density is $A/m^2$.

Explanation:

Electric current density is defined as the electric current flowing through a surface per unit area. It is given by :

$J=\dfrac{I}{A}$

We know that the SI unit of current is A and the SI unit of area is meter square. So, it is clear that the SI unit of electric current density is $A/m^2$. Hence, this is the required solution.
