Questions
Six identical conducting rods are joined as shown in figure. Points A and D are maintained at temperatures
respectively. The temperature of junction B will be
a
1000 C
b
140 C
c
1200C
d
800C
detailed solution
Correct option is B
If each rod has a thermal resistance R , resistance between B and C is also R (R and R are in series and 2R and 2R are in parallel)so temperature difference will be equally distributed i.e. across each rod it will be 200-203 =60 so 200-Tb=60 Tb=1400CTalk to our academic expert!
