Inner surfaec of a cylindrical shell of length l and of material of thermal conductivity k is kept at constant temperature T_(1) and outer surface of the cylinder is kept at constant temperature T_(2) such that (T_(1)gtT_(2)) as shown in figure. heat flows from inner surface to outer surface radially outward. inner and outer radii of the shell are R and 2R resspectively. Due to lack of space this cylinder has to be replaced by a smaller cylinder of length (l)/(2) inner and outer radii (R)/(4) and R respectively and thermal conductivity of material nk. if rate of radially outward heat flow remains same for same temperatures of inner and outer surface i.e., T_(1) and T_(2) then find the value of n.

Consider a hollow cylinder of length L and inner radius a and outer radius b, as shown in figure. The material has resistivity rho . (a) Suppose a potential difference is applied between te ends of the cylinder and produces a current parallel to the axis. What is the resistance measure ? (b) If instead the potential difference is applied between the inner outer surfaces so that current flows radially outward, what is the resistance measure ?
