Warmup3: do before recitation #4 Thursday/Friday February 8/9. Answers: (a) -3.0x10-6C (b) 1.310-5C, (a) 3.5pF (b) 3.5pF (c) 57V, 0.280F, 72F
Warmup4: do before recitation #7 Thursday/Friday March 1/2. Answers: 8.0 Ohms; (a) 0.004 Ohm (b) 1; (a) 50 mA (b) 60 mA (c) 9.0V; (a) 0.150 Ohm (b) 240 W

Practice Exams
These are exams from the equivalent MIT course 8.022, from fall 2002, 2004 and 2006.
Solutions are available for the fall 2002 exam here (that course used a different system of units -- you can convert your answers to theirs by setting k=1 and epsilon0=1/(4pi)). I'll post comments about the problems on the exams continuously over the weekend.
