  1. Chapters 19 & 20 DC Circuits Topics: • RC Circuits 1

  2. Textbook Choices I would prefer to buy a textbook … that comes as a single hardback text that can be used for Phys 151& 152. that comes in a loose leaf format that can be put into a three ring binder, can be used for Phys 151& 152, and costs 35% less than the hardback text. that comes as two paperback volumes, one for 151 and one for 152. The cost would be 20% more than the hardback text but would be split over 2 semesters.
