A coaxial cable consists of a solid inner conductor of radius R1 surrounded by a concentric cylindrical tube of inner radius R2 and outer radius R3 (the figure) The conductors carry equal and opposite currents Io distributed uniformly across their cross sections + add graphadd pointsdelete graphi graph inforeset?. let i0=1.50a, r1=1.00 cm, r2=2.00 cm, and r3=2.50 cm. graph b from r=0 to r=3.00 cm.
