From the latter equation, calculate the voltage V + in volts and write your answer: V + = ______ V Part 1 2 3 4 Total EECS 314 Fall 2008 Homework set ___ Student’s name ___________________________ Discussion section # _______ (Last, First, write legibly, use ink) (use ink) Instructor is not responsible for grading and entering scores for HW papers lacking clear information in the required fields above © 2008 Alexander Ganago Page 2 of 2 Problem 1, continued The ckt diagram is repeated here for your convenience. Part 2 (10 points) Write the node voltage equation for V – , first without using the GR and then after applying the GR, in the space below. From the latter equation, calculate the voltage V OUT in volts and write your answer: V OUT = ______ V Part 3 (10 points) From the the node voltages, calculate the currents I 10 , I 50 , and I 91 in mA and write your answers: I 10 = ______ mA I 50 = ______ mA I 91 = ______ mA Part 4 (10 points) From KCL, calculate the Op Amp's output current I OUT in mA and write your answer: I OUT = ______ mA Verify whether KCL is valid at the ground node. Write your conclusion: Yes / No (circle one) Do not be surprised by the possible “violation” of KCL: your calculation is incomplete, because the circuit diagram is incomplete, lacking the power supplies (such as – 12 V and +12 V), which can carry large currents! Show your work.
