Answer:
The current density in the sphere is 0.32 A/m²
Explanation:
Given that,
Current = 1.0 A
Diameter = 1.0 mm
Radius of sphere = 1.0 m
We need to calculate the current density in the sphere
Using formula of current density
[tex]J=\dfrac{I}{A}[/tex]
Where, I = total current
A = area of sphere
Put the value into the formula
[tex]J=\dfrac{1.0}{\pi\times(1.0)^2}[/tex]
[tex]J=0.32\ A/m^2[/tex]
Hence, The current density in the sphere is 0.32 A/m²
