Two identical long, thin, solid cylinders are used to conduct heat from a reservoir at temperature T_hot to a reservoir at temperature T_cold. Originally the cylinders are connected in series as shown in Fig. 23-24, and the rate of heat transfer is H₀. If the cylinders are connected in parallel instead as shown in Fig. 23-24b, then what would be the rate of heat transfer? (A) 16H₀ (B) 4H₀ © 2H₀

(D)H₀/2 (E) the answer depends on the thermal conductivity, K, of the cylinders.
