All the rods have same conductance `'K'` and same area of cross section '`A'`. If ends A and C are maintained at temperature `2T_(0)` and `T_(0)` respectively then which of the following is`//`are correct?

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 `(3KAT_(0))/(2a)`

D

Temperature at junctions B, O and D are same

Text Solution

Verified by Experts

By symmetry
`I_(AB)=I_(BC)&I_(AD)=I_(DC)`
`therefore` no current in BO and OD
`thereforeT_(B)=T_(O)=T_(D)`
