1. The problem statement, all variables and given/known data Homogeneous body with the shape of a truncated rotating cone has a base shaped like a circle. The radius of the lower base is R2 = 8 cm and radius of the upper base is R1 = 4 cm. The height h = 8 cm (see figure). Calculate the total electric resistance between the base surfaces of the body, when made of a material of resistivity ρ = 4*10 ^(-2) Ohm*m. Assume that during the transport of electric charge through the body volume, the current density changes. 2. Relevant equations see the picture 3. The attempt at a solution idea: triple integration..one through the height...and the remaining ones through the radius and the perimeter....but does this take into account the changing of the radius at different heights?
