일반물리학 2 — Capacitance: Problem 41

41 The capacitors in Fig. 25-37 are initially uncharged. The capacitances are \(C_1 = 4.0 \mu\text{F}\), \(C_2 = 8.0 \mu\text{F}\), and \(C_3 = 12 \mu\text{F}\), and the battery’s potential difference is \(V = 6.0 \text{ V}\). When switch S is closed, how many electrons travel through (a) point a, (b) point b, (c) point c, and (d) point d? In the figure, do the electrons travel up or down through (e) point b and (f) point c?
