The wye-delta transformation is a critical technique in electrical circuit analysis, particularly for simplifying complex resistor networks. However, it cannot be applied in certain special cases, such as when dealing with a cube of resistors or messy nets that include current and voltage sources. The discussion highlights the challenge of calculating resistance between opposite corners of a cube with equal resistances on all edges, emphasizing the limitations of the wye-delta transformation in these scenarios.
