일반물리학 2 — Current and Resistance: Problem 5

5 In Fig. 26-16, current is set up through a truncated right circular cone of resistivity \(731 \, \Omega \cdot \text{m}\), left radius \(a = 1.70 \, \text{mm}\), right radius \(b = 2.30 \, \text{mm}\), and length \(L = 3.50 \, \text{cm}\). Assume that the current density is uniform across any cross section taken perpendicular to the length. What is the resistance of the cone?
