JEE Main 2026 Physics question
Rods x and y of equal dimensions but of different materials are joined as shown in figure. Temperatures of end points A and F are maintained at C and C respectively. Given the thermal conductivity of rod x is three times of that of rod y, the temperature at junction points B and E are (close to):
Answer: (1)
Solution
Using series-parallel resistance network for heat flow gives C, C.
