A)Current= V/R
=22/0.015
=1466.67 A
B)
Currrent density=current/area
=1466.67/(pi*0.003^2)
=51872722.19 A/m^2
a)
I = V/R = 22/(15X10^-3) = 1.4666 X10^3 A = 1466.66 A
2)
area = 3.14 X(3^2)X(10^-6) m^2 = 28.26 X10^-6
current density = current/area = 1466.66/28.26X10^-6 = 51.898 X 10^6 A/m^2 = 518990327.905 A/m^2
