Delta-Wye conversions allow you to convert electrical circuits into an equivalent and easier to solve form. This is accomplished by converting a "delta" configuration of resistors into an equivalent "Wye" configuration of resistors. This video derives the equations for the conversions and describes the process to make the conversions.
00:21 - Why Delta-Wye
1:55 - Delta and Wye shapes
3:04 - Pi and Tee shapes
4:10 - Delta and Wye shapes with labelled resistors
4:40 - Identifying equivalent resistances between nodes in Delta and Wye configurations
8:00 - Solving the resistance equations for the Wye network (lots of algebra!)
12:15 - Re value determined
13:00 - Rd, Re, and Rf equations (for Wye network) in terms of Ra, Rb, and Rc (from Delta network)
13:30 - Mnemonic for remembering equations
