A) \[120{}^\circ C\]
B) \[150{}^\circ C\]
C) \[60{}^\circ C~~\]
D) \[80{}^\circ C\]
Correct Answer: A
Solution :
Equivalent electrical circuit will be as shown in the fig Temperature difference between A and D is \[{{180}^{o}}C\] which is equally distributed in all the rods. Therefore, temperature different between C and D will be \[{{60}^{o}}C\] or temperature of C should be \[{{180}^{o}}C\] So, the temperature at junction B \[{{180}^{o}}-\theta =\theta -{{60}^{o}}\] \[\theta ={{120}^{o}}C\]You need to login to perform this action.
