Category:Wye-Delta transform

The Y-Δ transform (‘wye’ or ‘star’ may be substituted for ‘Y’ and ‘delta’ or ‘triangle’ for ‘Δ’; order may be reversed) is a theorem of graph theory used most often in electrical engineering. The images in this category have different labels for their elements, but are otherwise equivalent.
