Tomorrow's quiz / HW2 solutions

Tomorrow's quiz covers three main topics: (1) adding identical capacitors in series or parallel, (2) potential energy change of a charge moving from one voltage to another, (3) relationship between a constant E field and potential difference (say, when moving through a distance x). I will give the quiz at the end of lecture, so things may be a bit clearer by that point anyway.

Also, I have draft solutions of HW2 ready, and will post them some time before I sleep. Probably around 2am, i.e., after the deadline. Check back here in the early AM.
