If the 22Ω resistor is replaced with ZL = 100Ω + -j100Ω, determine the following.

### Delta-Wye Transformer Configuration #### Diagram Explanation: The diagram shows a three-phase delta-wye transformer configuration. The primary side (delta connection) has three impedances labeled \( Z_L \) connected in a triangle. The secondary side (wye connection) is labeled with nodes A, B, and C, connected to a neutral point N. The phase voltages of the transformer are given as: - \( E_{AB} = 208 \, V \, \angle 0^\circ \) - \( E_{BC} = 208 \, V \, \angle \theta_2 \) - \( E_{CA} = 208 \, V \, \angle \theta_3 \) #### Required Calculations: 1. **Voltage across each phase impedance in phasor form:** - \( V_{ab} = \; \angle \; \) units - \( V_{bc} = \; \angle \; \) units - \( V_{ca} = \; \angle \; \) units 2. **Current through each phase impedance in phasor form:** - \( I_{AB} = \; \angle \; \) units - \( I_{BC} = \; \angle \; \) units - \( I_{CA} = \; \angle \; \) units 3. **Magnitude of the line current:** - \( I_L = \; \) units 4. **Magnitude of the generator phase voltage:** - \( E = \; \) units This setup is commonly used in power distribution systems to step down voltage levels while maintaining three-phase power, which is efficient for delivering electricity over long distances.
