The current density is a solid cylindrical wire a radius R, as a function of radial distance r is given by J(r )=J_(0)(1-(r )/(R )) . The total current in the radial regon r = 0 to r=(R )/(4) will be :

The current density in a cylindrical conductor of radius R varies according to the equation J=J_(0)(1-r/R) , where r=distacnce from the axis. Thus the current density is a maximum J_(0) ata the axis r=0 and decreases linealy to zero at the srface r=2/sqrtpi . Current in terms of J_(0) is given by n(J_(0)/6) then value of n will be.
