For the circuit shown,a) To the coil of a henry, measure its internal resistance and the value of the inductance.b) Measure the effective voltage and current at the terminals of the 100 Ω resistor and at the source.c) Measure the average power delivered by the source.Note the phase shift between the supply voltage and the voltage across the 100 Ω resistor (only at this point).
Company Y would like to have a new installation transmission line to open a small new city consist of 300 MW with 0.85 power factor lagging at full load. The new transmission line required 132 kV with 124.274 miles long. All the elements needed for the new transmission line is listed in table shown in the picture. You are required to model the transmission line and analysed the performance of the new transmission lines in terms of voltage regulation and efficiency. Note that the frequency used is 50 Hz.
