EECS 314 Winter 2009 Homework set 1 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 © 2009 Alexander Ganago Page 1 of 4 Scores for the HW set: Problem 1 2 3 4 5 6 7 Total Score Problem 1 KCL, KVL, and the Passive Sign Convention The Assignment Consider the circuit shown on this diagram. Note that nodes A, C and B are all connected with wires thus they are in fact one node! Some currents and some voltages in the circuit are given in the table below and on the diagrams on the following page; your challenge is to calculate the unknown voltages and currents, as well as the power absorbed by each element. Element 1 2 3 4 5 6 7 Current through 4 A 2 A 1 A 5 A Voltage across 48 V 6 V 12 V Power absorbed Part 1 2 3 Total Score
