Here are a few actual exams from past semesters. If you are using these to study, I highly recommend you work out the exams on your own BEFORE looking at the solutions. Also note that the coverage from year to year is not necessarily consistent, both in terms of overall material covered and material covered for each exam. In particular in Fall 2016 we covered more circuits than I plan to cover this semester, and the circuits topics were part of Exam 3. There may be other differences.
- Exam 1
- Exam 2
- Exam 2 - Spring 2016.docx | Exam 2 - Spring 2016 - solutions.pdf
- Exam 2 - Fall 2016.docx | Exam 2 - Fall 2016 - solutions.pdf- Oops, looks like there are a couple of errors in the solutions:
- Problem 1.9 (multiple choice) - my logic is good, but I accidentally wrote // instead of perpendicular in my description of the second boundary condition.
- I dropped a negative sign from the bound volume charge density of problem 5.
- Exam 3 - See note above about the difference in material from previous semesters
- Final Exam
- Final Exam - Spring 2016.docx | Final Exam - Spring 2016 - solutions.pdf
- Final Exam - Fall 2016.docx | Final Exam - Fall 2016 - solutions.pdf (with last page removed, since it's a current homework problem)
