ELEC 225: Circuit Theory I
Bucknell University, Fall 2002
Course Objectives:
Students finishing this course will
understand fundamental circuit analysis techniques, including
sinusoidal steady-state methods.
Students will be prepared to take ELEC 226 in the next semester,
which will include time-domain circuit analysis, Laplace transform
methods, and frequency analysis of circuits and signals using
Fourier series and transforms.
Instructors and Office Hours:
The course will be co-taught by Professors Margaret Wismer and
Rich Kozick.
Professor Kozick will teach the lectures
and Professor Wismer will teach the laboratories.
Office hour schedule for Professor Kozick for Fall, 2002 is
T 10-11 and 3-4, W 1-2, and F 1-2.
Other times can be arranged - talk to me in class, send email,
or call.
Refer to the
course home page for the most up-to-date office hours.
Prerequisites:
ELEC 120 and MATH 201, 202.
Corequisite: MATH 211.
Required Textbook:
Electric Circuits (Sixth Edition, Revised Printing),
by J.W. Nilsson and S.A. Riedel, Prentice-Hall, 2001.
The library has many books on circuit analysis.
We encourage you to read a variety of books in order to
see different explanations and additional examples.
Optional Supplement:
Introduction to PSpice Manual for Electric Circuits
(Fourth Edition), by J.W. Nilsson and S.A. Riedel, Prentice-Hall, 2000.
This supplement to the main textbook includes a CD with OrCad
Release 9.2 PSpice software (student version).
We will use PSpice in this course for homework and for labs.
You will also use PSpice in future courses.
Course Home Page:
The home page for the ELEC 225 course is located at
http://www.eg.bucknell.edu/~kozick/elec22502
It can also be accessed by following the link from
http://www.eg.bucknell.edu/~kozick
The course home page contains homework assignments and solutions,
syllabus, links to laboratory assignments,
and other course information.
Grading:
Grades for the course will be determined as follows.
Three in-class exams (10% each) 30%
Short quizzes and class participation 10%
Final exam 15%
Homework 15%
Laboratories 30%
Exams and Quizzes:
Three in-class exams will be given on the following dates:
Wednesday, September 25
Monday, October 28
Monday, November 25.
The course will conclude with a comprehensive final exam.
Short quizzes (announced or unannounced)
will also be given to check your understanding of
the material as we proceed through the course.
Missed quizzes cannot be made-up, but your lowest quiz grade will be
dropped.
We will also do in-class exercises (individually and in groups)
that will be counted toward the "Short quizzes and class participation"
grade component.
Homework:
Homework will be assigned regularly to give you practice
with the course material.
It will be due at the beginning of class on the specified due date.
Late assignments will not be accepted because solutions will
be distributed and reviewed during class on the due date.
You are allowed and
encouraged to work on the homework with groups of your classmates.
The purpose of the homework is to practice with the material and to
improve your understanding.
We encourage you to learn from each other, and also to ask us when you have
questions.
However, the homework solutions that you submit for grading
must be written individually.
Be sure that you understand the reasoning for each problem,
even if you initially solved the problem with help from your classmates.
Laboratories:
Laboratories will be held every other week, on
the following dates:
September 5 and 19
October 3, 17, and 31
November 14
December 5
Please refer to the link on the course home page
for Professor Wismer's lab materials.
ABET Course Outcomes:
Please see the
ABET link on the course home page.
