electrical network homework

Name:__________________

Directions:

 There are six questions. o The first five questions are required and worth 20 points each. o The last questions is worth 2 points extra credit.

 You are expected to solve each problem completely and independently o The exam is open book, open notes. o Matlab may be used, however answers must be hand written on green engineering paper. o No work, No credit, No Exceptions. o The exam is due no later than 11:00 AM on Thursday, 6Feb14
