Physics - Heat & Thermo Question with Solution | TestHub

Two insulating sheets of thermal resistance $R_1=2$ and $R_2=3$ (in arbitrary units) are stacked. The temperatures on the outer sides are ${\theta }_1=100^{\circ }$C (next to $R_1$) and ${\theta }_2=0^{\circ }$C (next to $R_2$). Find the temperature $\theta$ at the interface in ${}^{\circ }$C.
