Design a system using the photoconductive cell to measure and display light intensity. Make the design such that 20 to 100 mW/cm2 produces an output of .2 to 1.0 V. What is the readout error when the intensity is 60 mW/cm2? I have to have a multisim design for the circuit to show the solution is correct. As well as all showing all work on calculations.
Discuss the methods used for finding the approximate transformer parameters Rser, Lser, Rpar, and Lpar and explain what each of the parameters Rser, Lser, Rpar, and Lpar model and show their positions in the transformer's circuit diagram.
The total power delivered to a balanced, Y-connected, three-phase load is 720 kW at a lagging power factor of 0.8. The line voltage at the load is 3463 V. The impedance of the transmission line is 2.5 + j10.2 ohm. a) Determine the line voltage at ..
