The beta B of a bipolar transistor shown below varies from 12 to 75. The load resistance is RC=120. The DC supply is VCO40V and the input voltage to the base circuit is Ve=6V. I VCE (= 1.2V, Vee(sat) 1.6V and Rs.0.70, then the overdrive factor ODF would be: Select one: 2.93 A single-phase full-wave converter in the figure below is supplied with a 120-V, 60-HZ source. The load is highly inductive and the load current is continuous and free of ripples. The electromotive force is neglected (E =0) and the resistance has a value of R - 10. The average output voltage 6 85% of the maximum possible average output voltage. The delay angle would be equal to Select one L15 670 A three phase full wave rectifier is shown below along with peak phase voltage V-1697V. The load is purely resistive The rectifier delivers toc=100 A and the source frequency is 60 Hz The DC output voltage is Voc=280.7V and the output RMS voltage is equal to VRMS 280 93V The efficiency, FF and RF are respectively equal to Select one 1600, 4 W 00001
