Two slabs A and B of different materials but of the same thickness are joined end to end to form a composite slab. The thermal conductivities of \(\mathrm{A}\) and \(\mathrm{B}\) are \(\mathrm{K}_{1}\) and \(\mathrm{K}_{2}\) respectively. A steady temperature difference of \(12^{\circ} \mathrm{C}\) is maintained across the composite slab. If \(\mathrm{K}_{1}=\frac{\mathrm{K}_{2}}{2}\), the temperature difference across slab \(\mathrm{A}\) is 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
