Answer 1

S.I unit of current density is $A/m^2$

Explanation:

We have to find the S.I unit of current density

Current density is given by $current\ density=\frac{current}{area}$

S.I unit of current is ampere and S.I unit of area is $m^2$

As current density is ratio of current and area  

So S.I unit of current density will also be ratio of S.I unit of current and S.I unit of area

So S.I unit of current density is $A/m^2$
