Question: Suppose a synchronous generator is supplying power at (RMS) voltage V to a load characterized by impedance Z 0 = R 0 + iX 0

Suppose a synchronous generator is supplying power at (RMS) voltage V to a load characterized by impedance Z0 = R0 + iX0 = z0eiφ0, when an inductive load with negligible resistance Z1 = iωL is added in parallel with the original load. Show that the real power delivered by the generator does not change. What is the change in reactive power? Similarly show that if a purely resistive load Z1 = R1 is added in parallel to the original load, the reactive power in the circuit does not change and compute the change in the real power.
