Figure shown below represents, parallel combination of two metallic slabs of same thickness having area of cross sections 2 m and 3 m respectively, connected to the same temperature difference. If the thermal conductivities of each slab is 300 W/mC, then equivalent thermal conductivity is (in W/m°C) T T2 k k
