The step down DC chopper uses DC source voltage V(dc) = 200 V and resistive load impedance of 10 ohm. The duty cycle is 0.4 the voltage drop across the switch may be taken as zero, Calculate :   (a) Average and RMS value of output voltage.  (b) Average and RMS value of output current.

A single-phase, 120V(rms),60Hz source supplies power to a series R-L circuit consisting of R=10 and L=40mH. (a) Determine the power factor of the circuit and state whether it is lagging or leading. (b) Determine the real and reactive power absorbed by the load. (c) Calculate the peak magnetic energy Wint stored in the inductor by using the expression Wint=L(Irms)2 and check whether the reactive power Q=Wint is satisfied. (Note: The instantaneous magnetic energy storage fluctuates between zero and the peak energy. This energy must be sent twice each cycle to the load from the source by means of reactive power flows.)

A single-phase AC voltage controller has a resistive load R = 10 Ohm, and the RMS input voltage is Vs = 230 V, 60 Hz. The delay angle is 120 degree. Then the RMS output voltage is: Select one: O a. 101 V O b. 39 V O c. None of the above O d. 143 V O e. 215 V

Please answer all questions 1. Calculate the magnitude (in RMS) of the current through R1 2. Calculate the magnitude (in RMS) of the current through R2. Simulation  1. Construct the circuit in Figure 2 in the Circuit JS simulator. Note that transformers in Circuit JS may be unstable. It is suggested to draw them by clicking from the bottom left corner to the top right corner and refresh your simulation before taking a measurement. 2. Perform a simulation, displaying the voltage across the voltage source, the current through R1, and the current through R2 in a “stacked” scope.  Display the RMS average for each trace. Include a screenshot.  Analysis 1. Compare the simulation results for the currents through R1 and R2. What is the percentage difference between the calculated and simulated value for each? Comment on why there may be a discrepancy.

A 500 MVA synchronous machine has H, = 5.6 MJ/MVA and a 1200 MVA machine has H₂ = 2.0 MJ/MVA. The two machines operate in parallel in a power station. What is the equivalent. H constant for the two, relative to a 100 MVA base?
