16 July--- Click here for Exam 2 results     Most of you did very well on this one.

As many of you know, there were difficulties in getting this exam formatted and printed on time.  Three of the diagrams had to be put on the blackboard and there were a couple of errors that I didn't catch.   These had to be corrected later and after careful review and discussion we decided to delete question 2 [see below].  The exam has been rescored to reflect these corrections.

Click here to view Exam 2   Correct answer is (1) for all, except:  question 10 where correct answer is (5), and question 16, where either (1) or (4) is acceptable: in the diagram as printed, the current could be traveling either to the right or to the left. 

NOTE: Question 2 has been deleted from the scoring: as printed, it was  not  as composed for the exam and the meaning was ambigous to many readers.  Thus this is now a 19-point exam.   The approximate letter grades are unchanged.  

08 June----Due to a copy transposition error, one exam question ["If a resistor obeys Ohm's law its resistance…….."] was scored incorrectly. The correct answer is "None of these." This error has been corrected and revised exam scores are now posted. The class average is 12.2, not a significant change. Published approximate letter grade ranges are unaffected.

04 June----Exam 1  results are ready.  Exam papers will be returned Tuesday.   Click here for exam results NOTE:   Results of this exam become permanent  on 10 June; any questions about  scores, errors, a make-up if you missed it, etc., must be resolved by or before  that date.
