6 01 Spring Semester 2008 What to Write for PS 8 Revised for Design lab 1 MASSACHVSETTS INSTITVTE OF TECHNOLOGY Department of Electrical Engineering and Computer Science 6 01 Introduction to EECS I Spring Semester 2008 What to Write for PS 8 Revised for Design lab Question 1 Nothing Question 2 Without changing anything else what if we did c solve n1 What changes in your solution Is this solution physically different could you see the difference with your multimeter from what you got before Explain Question 3 Nothing Question 4 Nothing Question 5 For this same version of the circuit without the wire between n2 and n4 a Intuition If we were to take the voltage source in this same circuit pull it out and turn it around so that the terminals were connected the other way without changing anything else would that change the voltages and currents in the actual physical circuit that is the values that you can measure with your multimeter Explain b Using solver If you were to change the entry VSrc vc n2 n3 to VSrc 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 multimeter what you got before Explain Question 6 Draw circuits Question 7 Nothing Question 8 Roughly determine the smallest value of op amp gain K for which Vout Rf Vin Rin is accurate to within ten percent Explain how you did it Question 9 Nothing Question 10 Nothing 6 01 Spring Semester 2008 What to Write for PS 8 Revised for Design lab 2 Design Lab Questions 15 and 16 will be made part of design lab 9 and should not be included in in the lab 8 write up You will have time in lab 9 to finish your circuits if you didn t finish during design lab 8 If you didn t finish the circuits for questions 11 14 of this lab though you should come in and finish them during office hours and describe your results in the lab 8 write up Question 11 Nothing Question 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 terminals when the potentiometer is at its two extreme positions Post lab Homework Use the circuit solving software to help answer the questions For each one submit the the Circuit you constructed and the output it generated when you solved it Show which values in the output correspond to answers to the questions we ask below No further explanation is required
