1. Given three capacitors, C1 = 2.0 F, C2 =1.5 F, and C3= 3.0 F, what arrangement
of parallel and series connections with a 12-V battery will give the minimum
voltage drop across the 2.0-F capacitor? What is
the minimum voltage drop?

2. Suppose three parallel-plate capacitors,
whose plates have areas A1, A2, and A3 and
separations d1, d2, and d3, are connected in
parallel. Show, using only Eq. 242, that Eq. 243 is valid.
