2. Consider the circuit on the left with R1 = 1 0, R2 = 2 0, R3 = 3 0, C2 = 2/F, and C3 = 3/F. Both capacitors are initially uncharged when the switch S, is closed at t = 0. (a) Write an equation for the current, (t), passing through Ri using the numerical values provided. (b) What is the final charge on C2, a long time after the switch S, is closed? (c) Next we also close switch $2. What are the final charges on the capacitors, Q2 and Q3, a long time after the switch S2 is closed? A Physics 158 student forgets to discharge these two capacitors before disconnecting them. The next day another P158 student reconnects them with reverse polarity as shown in the figure on the right. (d) Calculate | Vab | and | Ved | a long time after the switch S2 is closed. (e) How much charge flows through the switch S2? a d WWW a S , R C3 R2 R W 24 V S, C, C. C b C b d
