NO CELL PHONES are allowed during lecture. 2. Be on time to class. Tardy is discouraged. 3. No late assignments will be accepted. Medical or family emergency will be considered on case-by-case basis. 4. No make-up exams/quizzes. If you miss the exam, a zero score will be assigned to the missed exam/quiz. No electronic devices other than a calculator will be allowed. 5. If you miss a class due to personal emergency or medical reasons, please be sure to inform the instructor by e-mail. 6. Homework assignments are to be submitted by the due date. You should keep a record of your homework in HW notebooks or HW binder and be ready to present it upon request. You may discuss homework problems with your classmates, but you are responsible for your own works. 7. You are encouraged to read the sections in the textbooks related to the covered topics prior to the lecture as well as after. 8. Each student should use only his/her own clicker for quizzes. 9. After an assignment grade has been posted online, students must see the instructor within one week if they wish to discuss the assignment and their work. 10. University's rules on academic honesty concerning exams and individual assignments will be strictly enforced. See UC Conduct Standards: http://studentlife.ucmerced.edu/what-we-do/student-judicial-affairs/uc-conduct-standards a. Each student in this course is expected to abide by the University of California, Merced's Academic Honesty Policy. Any work submitted by a student in this course for academic credit will be the student's own work. b. You are encouraged to study together and to discuss information and concepts covered in lecture and the sections with other students. You can give "consulting" help to or receive "consulting" help from such students. However, this permissible cooperation should never involve one student having possession of a copy of all or part of work done by someone else, in the form of an e mail, an e mail attachment file, a diskette, or a hard copy. Should copying occur, both the student who copied work from another student and the student who gave material to be copied will both automatically receive a zero for the assignment. Penalty for violation of this Policy can also be extended to include failure of the course and University disciplinary action. c. During examinations, you must do your own work. Talking or discussion is not permitted during the examinations, nor may you compare papers, copy from others, or collaborate in any way. Any collaborative behavior during the examinations will result in failure of the exam, and may lead to failure of the course and University disciplinary action. Accommodations for Students with Disabilities: The University of California Merced is committed to ensuring equal academic opportunities and inclusion for students with disabilities based on the principles of independent living, accessible universal design and diversity. I am available to discuss appropriate academic accommodations that may be required for student with disabilities. Requests for academic accommodations are to be made during the first three weeks of the semester, except for unusual circumstances. Students are encouraged to register with Disability Services Center to verify their eligibility for appropriate accommodations. CIRCUIT PARAMETERS AND FUNDAMENTAL LAWS I Electric charge.
