6.01, Spring Semester, 2008—What to Write for PS 8: Revised for Design lab 1MASSACHVSETTS INSTITVTE OF TECHNOLOGYDepartment of Electrical Engineering and Computer Science6.01—Introduction to EECS ISpring Semester, 2008What to Write for PS 8: Revised for Design labQuestion 1: NothingQuestion 2: Without changing anything else, what if we did:c . solv e ( ’ n1 ’ )What changes in your solution? Is this solution physically different (could you see thedifference with your multimeter) from what you got before? Explain.Question 3: NothingQuestion 4: NothingQuestion 5: For this same version of the circuit (without the wire between n2and n4):a. Intuition: If we were to take the voltage source in this same circuit, pull it out, andturn it around so that the terminals were connected the other way (without changinganything else), would that change the voltages and currents in the actual physicalcircuit, that is, the values that you can measure with your multimeter? Explain.b. Using solver: If you were to change the entryVSrc ( vc , ’ n2 ’ , ’n3 ’)toVSrc ( vc , ’ n3 ’ , ’n2 ’)What changes in the solution printed by Python (ignoring tiny numerical differences)?Is this solution physically different from (could you see the difference with your multi-meter) what you got before? Explain.Question 6: Draw circuitsQuestion 7: NothingQuestion 8: Roughly determine the smallest value of op-amp gain, K, for whichVoutVin= −RfRinis accurate to within ten percent. Explain how you did it.Question 9: NothingQuestion 10: Nothing6.01, Spring Semester, 2008—What to Write for PS 8: Revised for Design lab 2Design LabQuestions 15 and 16 will be made part of design lab 9 and should not be included inin the lab 8 write-up. You will have time in lab 9 to finish your circuits if you didn’tfinish during design lab 8. If you didn’t finish the circuits for questions 11 - 14 of thislab, though, you should come in and finish them during office hours and describe yourresults in the lab 8 write-up.Question 11: NothingQuestion 12: Explain what happens with the motor.Question 13: Explain what happens with the motor and, if it’s different from the previous case,why.Question 14: Draw a schematic diagram of your circuit. Show the voltage at the motor termi-nals when the potentiometer is at its two extreme positions.Post-lab HomeworkUse the circuit-solving software to help answer the questions. For each one, submit the the Circuityou constructed and the output it generated when you solved it. Show which values in the outputcorrespond to answers to the questions we ask below.
