Answer:
The current is
Explanation:
From the question we are told that
The radius is
The current density is
The distance we are considering is
Generally current density is mathematically represented as
Where A is the cross-sectional area represented as
=>
=>
Now the change in current per unit length is mathematically evaluated as
Now to obtain the current (in A) through the inner section of the wire from the center to r = 0.5R we integrate dI from the 0 (center) to point 0.5R as follows
substituting values
