Unformatted text preview: source to the loads. 4. What is the power factor of the three loads combined? 5. It is necessary to add a parallel load in the Δ configuration to the circuit to change the power factor of all loads combined to 0.875 lagging. The line voltage and total average power delivered by the source may not change. What are the impedance and the component value of this load? 6. What is the power factor of the additional load? 7. What is the power factor of the four loads combined?...
