ORGANIZATION: 1. Homework will be assigned every two weeks on average. Midterm and final exams are closed books and will be cumulative. You are not allowed to bring anything to the exam, except a calculator. Quizzes are also closed books. No "cheat-sheet" is allowed in exams and quizzes.

2. Under absolutely no circumstances there will be make-up exams or quizzes. You are permitted to miss one homework, and one quiz. The missed assignments will not count. For students that take all quizzes and turn in all assignments, the lowest grade assignments will be dropped. Any additional missed quiz will count as zero towards the final grade. There will be no exceptions.

3. Students are permitted only 3 late days per semester to use for homework and lab reports (not pre-labs). Beyond these 3 late days for homework and lab write-ups, no late work will be accepted unless arrangements have been made in advance for what is deemed necessary reasons (e.g. family illness, etc...).

4. Excused absence from the midterm exam must be obtained in advance. Excused absences will be made only in extreme circumstances (serious illness, etc.). Unexcused absences from the midterm will result in a grade of zero for that exam. Requests for excused absences should me made in advance and must be supported by appropriate documentation (e.g., a doctor's note). If the final exam is missed then the grade will be automatically an F. I almost never give an I (incomplete), unless there is a very justified medical reason.

2007-2009 Catalog Course Description: Educational Goals:

Basic circuit analysis: resistive circuits, voltage and current This first course, circuit theory, is designed to sources-independent and dependent. Nodal and mesh familiarize students with the analysis and design of analysis. Network theorems. Energy storage elements. RC, basic circuits. This course covers resistive circuits, RL, and RLC transient and steady state analysis, phasors, dependent sources operational amplifiers, energy, SPICE analysis. (3 hrs lecture, 3 hrs lab) storage elements, first and second order circuits, AC excitation and phasor, steady state analysis and power, Pre-requisite: PHYS 2011 and three-phase circuits: the laboratory component of Co-requisite: MATH 3280 the course provides students an opportunity to use instruments, such as scopes and meters for measuring voltages and currents in different-circuits. In addition, Course Objectives: students will have the opportunity to analyze and design circuits using PSPICE.  Master resistive circuits. (a.b,c,e,n) Clear documentation of lab results and a formal report  Introduce dependent sources and are required. Comparison of lab and theoretical results operational amplifiers.

(a,b,c,e,i,k,n)

 Incorporate energy storage elements such as  Introduce students to the first course in circuit inductors and capacitors in circuit analysis. analysis. (a,b,c,e,i,k,n)  Requires students to apply integral and  Master first and second order circuits.(a,b,c,e,i,k,n) differential calculus in order to study circuit response.  Analyze sinusoidal sources using phasors. (a,b,c,e,i,k,n)  Prepares students to analyze and design advanced circuits.  Emphasize AC steady state analysis and power. (a,b,c,e,i,k,n)  Exposes student to AC analysis and prepares them to take courses in power, control systems and electronics. Accreditation Outcomes Addressed By This Class: (Students should demonstrate :….) a. an ability to apply knowledge of mathematics, science and engineering b. an ability to design and conduct experiments, as well as to analyze and interpret data b. an ability to design a system, component, or process to meet desired needs e. an ability to identify, formulate, and solve engineering problems. g. an ability to communicate effectively. i. a recognition of the need for, and an ability to engage in life-long learning k. an ability to use the techniques, skills, and modern engineering tools necessary for engineering practice. n. an ability to work in a hands-on laboratory in most of the required courses.

*A ‘D’ represents achievement that is worthy of credit but does not meet the class requirements. An ‘F’ represents work that is not worthy of credit or no prior agreement between the student and instructor that an ‘I’ (Incomplete) would be awarded such that the student would subsequently complete the necessary work to receive a grade (as defined by http://www.fpd.finop.umn.edu/groups/senate/documents/policy/gradingpolicy.html).

Students are expected to conducts themselves in a manner that is respectful of both the instructor and other students. Furthermore, sexual harassment of any form will not be tolerated. Individuals who have any disability, either permanent or temporary, which might affect their ability to perform in the class, are encouraged to inform the instructor at the start of the semester. Adaptations may be made as required to provide for equitable participation.
