Consider a non-perfect conductor of re-sistivity p and shaped like a slice of pineap-ple. Its inner radius is R1, its outer radiusR2, and its thickness is h.Two perfectly conducting terminals areattached to it: one covers the entire in-ner cylinder and the other covers the entireouter cylinder.The disk-shaped top and bottom of theRgR2slice are covered in perfectly isolating material.Determine the resistance, with the help of the following hints:1. Work in cylindrical coordinates (z,r, ø), with the z-axis placed along the conduc-tor's central axis.2. Assume that the electric potential V inside the non-perfect conductor depends onr only, and not on z and not on ø (this can be proven, but we don't do that here).
