The circuit shown in Figure 1 is a simplified DC version of an AC three-phase wye-wye (Y- Y) electrical distribution system commonly used to supply industrial loads, particularly rotating machines. Given: Vs1 = Vs2 = Vs3 = 170 V Rw1 Rw2 Rw3 = 0.70 R₁ = 1.9 Q R₂ = 2.3 Q R3 = 110 a. Determine the number of non-reference nodes. b. Determine the number of unknown node voltages. c. Compute v'1, v'2, v'3, and v'n. Notice that once v'n is known the other unknown node voltages can be computed directly by voltage division.
