Review session for final exam: Fri June 6, 5:30-7:30, Wil 110.

May 28
HW #8 is posted below. Note there are two problems on a separate page based on the AC Circuits handout (one of the two is extra credit).

May 28
Handout on AC Circuits to replace Sections 30.7-30.9 of text.

May 23
Figure from class today on LC circuit

May 5
Here is the web page I showed in class about the Celilo DC power station and transmission lines.

Apr 29
I still have free copies of Vol III of Giancoli 4th Ed. Many of you got this in class. If not, you can stop by my office to get one. This is completely optional.

Mar 12
Note on textbook: We will be using Vol II (only) of Giancoli, 4th Ed. Students already enrolled in the Kribs/Frey sections of 251/252 should have this. Students coming into 253 from the van Enk section of 251-2 will need to get it. The UO Bookstore has a few copies of the Vol I+II set on sale.
But they also have ordered 20 copies of Vol II only (as of 3/12 it is not yet on the shelves). It is only a little cheaper than the set. They also have some used copies (just make sure you are getting the right book).

Course Description:
This term we will study electromagnetism (aka E&M). This corresponds to Chapters 21-31 of the text (Vol II).
We will start with electric charge, electric field, and potential; then steady currents and DC circuits; magnetic fields; finally getting into time dependent fields and
the full Maxwell equations from which electromagnetic radiation was predicted. As recognized by Einstein, Maxwell's theory of E&M turned out to be fully consistent
with Special Relativity, and so in this sense was the first modern physics theory.

Homework:

Weekly homework will be assigned from the text and will be due as posted above..
Students are required to show their work and reasoning as appropriate to receive full credit.
You are welcome to work on the homework with your classmates, and please feel free to seek help from me. The work you turn in must be entirely your own, of course. (Note that the Physics Reading Room in Willamette Hall is available to use to collaborate on assignments, discuss deep thoughts, etc.)
Complete solutions will be available from this web site soon after the due date. Please refer to these.
Late homework penalties..

Exams: There will be two midterms and one final exam. Exams will be closed book, but the generally useful equations and information will be provided. Problem solutions need to include all work necessary to demonstrate the result. Practice exams and solutions will be provided approximately one week before an exam. The dates for midterms will be announced at least 8 days before the exam.
