What's All This Tee Network Stuff, Anyhow?

摘要

A few dozen years ago, somebody asked me how to compute the transform between a TEE (or WYE) of resistors and the DELTA of resistors shown in the figure. I did all of the calculations and posted a copy of them inside a cabinet. The equations stayed there for over 10 years, until I neglected to transfer them to my new cabinet. Now, because somebody asked me to, I must do them again. Note that I show a tentative connection among the three legs of each network, as if to summing point, ground, and V_(OUT')' which is typical. But these resistor networks can be connected to any circuit.
