Homework Equations
To simplify the resistors we use a Wye-Delta transform so:
R1 = RbRc/(Ra+Rb+Rc)
R2 = RcRa/(Ra+Rb+Rc)
R3 = RaRb/(Ra+Rb+Rc)
Then the Kirchoff current law on the nodes to calculate i(o).
The Attempt at a Solution
I can do the Wye-Delta transform no problem, but am having serious trouble in calculating i(o). After that it's a fairly straightforward problem.
Any help would be massively appreciated!
