Description:
Advanced analysis of resistive and reactive passive networks under direct and alternating current
excitation; Thevenin’s and Norton’s Theorems, loop and nodal analysis, superposition, Delta-Wye
transformations; practical transformers; resonant circuits; DC and AC bridges; coupling networks.

Your instructor may require you to use only a CASIO FX991 MS basic scientific calculator during
exams (including term tests, quizzes …). One will be loaned to you for the exam. You may wish
to purchase one of your own in order to become familiar with its operation but the department’s
calculator will be used during exams. This policy has been adopted to make exams fair for all
students.
No other devices are allowed during exams such as MP3 players, cell phones or PDA’s.
Students must obtain at least a 50% average in both their Lab Marks and Exam Marks to qualify
for a grade above D (54%).
Students must attend & complete at least 90% of the labs to qualify for a grade above F (49%).
Students are to hand in, on time, a neat copy of all assignments and lab reports.
Students handing any work in late (labs, assignments), will have their mark for that work de-rated.
Students arriving late for any lab will have their mark for that lab de-rated.
