**Delta ⇌ Wye Transformations**

Three impedances connected nose-to-tail, as shown in Figure 25.1, are said to be delta (Δ) or mesh connected, because they form a mesh.

Three impedances connected together to a common point, as shown in Figure 25.2, are said to be star (or *Y*) connected.

If their nodes (1, 2 and 3)—to which the two ...
