A factory receives power at 480 Vrms @ 60 Hz. from the electric utility company. The factory’s electrical load can be simply represented by 2 loads. LOAD1 describes the manufacturing equipment on the assembly line. LOAD2 describes the power used in office rooms. From time to time, the assembly line shuts down thereby removing LOAD1 from the grid. SWITCH1 accounts for this effect in the equivalent circuit model shown above. Note that the 2 dependent sources represent a device called a “transformer” that steps the 480 Vrms down to 120 Vrms for use in the offices. (But don’t take my word for it; circuit analysis calculations will confirm this.) Given: Receiving End Voltage (with SWITCH1 closed): RV = 480 Vrms Wiring parameters: RW = 0.005 Ω, LW = 0.52052 mH Find: a) With SWITCH1 closed, find the value of C (in Farads) so that the total LOADt at the Receiving End has unity pf. Find the magnitude of the Sending End Voltage SV , and the magnitude of the “Office” load voltage, 2V. Note that RMS480VRV= for this case. b) With SWITCH1 open, using the value of C and SV found in part a), find the new values of the magnitudes of the Receiving End Voltage RV and Office Voltage 2V. Why will this be a problem for the office? How could you change the capacitor connection to avoid this problem? Hints: Note that no phase angles were given, and only magnitudes were asked for. You can choose one voltage or current to have 0 degree phase angle and then allow the calculations of any other voltages and currents be relative to that. In part b) RMS480VRV≠.

Discuss the following questions and topics. Interact with at least two other students and do more than just agree with their comments. Provide expanded ideas or other informative comments related to their posts. What is the difference betweenqualitative and quantitative research? Given the topic you havechosen to study and assuming you were going to use a qualitative approach,which of the five designs (case, ethnography, phenomenological, grounded theoryor content analysis) would be best suited to answer your research questions?Explain your decision. Review the approachesdiscussed in your text for collecting quantitative data and determine which(sampling, observation, or interview) might be best suited for your study.Explain your decision. When conducting interviewswhy is it critical to develop specific interview questions? Is it useful to includescaled questions (e.g., Likert scale such as 1 to 5) as part of your structuredinterview questions? Why or why not? Should open-ended questionsbe included? Why or why not? What are useful data sourcesfor conducting historical research?
