A signal generator has an output voltage of 2.0 V with no load. When a 600 W load is connected to it, the output drops to 1.0 V. The Thevenin voltage of the generator is1.0 V2.0 V4.0 Vnot enough information to tell.

A signal generator has an output voltage of 2.0 V with no load. When a 600 W load is connected to it, the output drops to 1.0 V. The Thevenin resistance of the generator is300 ohms600 ohms900 ohms1200 ohms

Given the normalised load impedance is zL  = 0.4+1.4j on a 50 Ω transmission line system (you may use Smith chart to answer the question):Select one:a.The load reflection coefficient is |ΓL| = 0.8 and theta =68 degb.The VSWR changes as we move along the line toward the generatorc.The voltage standing wave ratio is VSWR=2d.The voltage standing wave ratio is VSWR=5e.The load reflection coefficient is |ΓL| = 0.6745 and theta =26.5 deg

The generator output voltage is then increased to 132 kV for transmission. Explain why electrical energy is transmitted using very high voltages.

Explain why the d.c. from the generator must be changed to a.c. before it is transmitted.

1. Transformer Per-Unit AnalysisA power system consists of a generator rated at 500 MVA, 20 kV, and a transformer rated at500 MVA, 20/230 kV with an impedance of 0.01 + j0.05 per unit on its own base. Thetransformer is connected to a transmission line with an impedance of 0.02 + j0.1 per unit ona 230 kV, 500 MVA base.a. Convert the transformer impedance to the generator base.b. Calculate the per-unit impedance of the transmission line on the generator base.c. Determine the total impedance of the system (generator, transformer, and transmissionline) in per-unit on the generator base.
