Six identical rods are joined as in the diamond figure: $A$ is joined to $B$ by one rod, $B$ to $C$ by two parallel paths of two rods each, and $C$ to $D$ by one rod. $A$ is at $10 0^{\circ}$ C and $D$ at $1 0^{\circ}$ C. Find the temperature of $B$ in $^{\circ}$ C.

Answer:

Solution:

The resistances are $r$ , $r$ and $r$ in series. The drop across $A B$ is $\frac{90}{3} = 30$ , so $T_{B} = 100 - 30 = 7 0^{\circ}$ C.
