               Subtracting eq. (2) from eq. (1)








               Adding eq. (4) with eq. (3)








               This way by solving eqs. (1), (2), and (3), R , R , R  can be found.
                                                                    1
                                                                             3
                                                                         2
                  Thus, when delta-connected resistances are changed to an equivalent star-
               forming resistances, their values are:
