Chapter 22: 9, 22, 33, 37, 51, 55

Chapter 23: 3, 19, 26, 38, 44, 61

Topics include  current, voltage, total charge that flows, resistivity, electric field and potential difference, power, circuit diagrams, resistors and circuits in series and parallel (including equivalent resistance and capacitance), current and voltage in circuits, RC circuits.

Even solutions: chapter 22:

22: 50 ohm meters

chapter 23:

26: 1 A & 5V.  5V & 0.5 A, 2.5 V & 0.5A, 2.5 V & 0.5 A

38: a) 1.87 microfarads

b) 2.24 x 10^-5 C

44: a) 1.8 x 10^-5 C, zero amps
