A) Rate of heat flow through ABC, AOC and ADC is same
B) Rate of heat flow through BO and OD is not same
C) Total Rate of heat flow from A to C is \[\frac{{{P}_{o}}}{{{P}_{He}}}=\frac{1}{8}\]
D) Temperature at junctions B, O and D are same
Correct Answer: D
Solution :
[d] By symmetry \[{{I}_{AB}}={{I}_{BC}}\] and \[{{I}_{AD}}={{I}_{DC}}\] \[\therefore \] No current in BO and OD \[{{T}_{B}}={{T}_{O}}={{T}_{D}}\]
