Three rods A, B and C of same length and same cross-section area are joined as shown in the figure. Their thermal conductivities are in the ratio 1 : 2 : 1.5. If the open ends of A and C are at 200°C and 18°C respectively, the temperature at the junction of A and B in equilibrium is-
Text Solution
Verified by ExpertsThe correct answer is:
B
T AB = 200 – IR A = 200 – 
= 200 – 
= 116°C
