Consider 2 cylindrical conductors whose cross sections are shown below. Two conductor They both have the same external radius b, but the conductor to the right is hollow and its internal radius a is such that b minus a equals q delta where delta is the skin depth of the material. For which value of q the two conductors practically carry the same current? 1. q=0.01 2. q=0.1 3. q=1 4. q=5
