(a) Find equivalent resistance respect to terminals A and B.
(b) Find equivalent resistance respect to terminal A and C.
redrew the diagram using iCircuit app
First I counted the all the node (8 nodes)
In series:
31 + 25 = 56Ω
38 + 29 = 67Ω
then I redrew the diagram
parallel:
67//26//39//23 = 6.65Ω
26//30 = 13.93Ω
32//34 = 16.48Ω
I redrew again
21 + 6.65 = 27.65
24//32//27.65 = 9.17
Now I saw that the 16.48 resistor is shorted
I redrew again
27//32 = 14.64
13.93 // 56 = 11.15
11.15 + 37 = 48.15
48.15//14.64//9.17 = 5.04 Ω
But the answer for part (a) is 13.07Ω.
I can't seem to find the error in my computation...
