DC CIRCUIT ANALYSISBasic DC TheoryStep 4: Find I2 and I3. The voltage across R1 and R2 is equal to the applied voltage (V),minus the voltage drop across R1.V2 = V3 = V - ITR1 = 60 - (7.5 X 4) = 30 VThen, I2 and I3 are calculated.I2V2R23065 ampsI3V3R330122.5 ampsYandDeltaNetworkCalculationBecause of its shape, the network shown in Figure 47 is called a T (tee) or Y (wye) network.These are different names for the same network.Figure 47 T or Y NetworkES-02 Page 60 Rev. 0
