Five identical rods are joined as shown in figure. Point A and C are maintained at temperature 120°C and 20°C respectively. The temperature of junction B will be
Text Solution
Verified by ExpertsThe correct answer is:
C
If thermal resistance of each rod is considered R then, the given combination can be redrawn as follows
(Heat current) AC = (Heat current) AB
$\frac{(120-20)}{R} = \frac{(120-\theta)}{R} \Rightarrow \theta = 70^\circ C$
