Capacitor circuit As shown in the figure, capacitor1 (C1=8.0μF), capacitor2 (C2=6.0μF), and capacito3 (C3=8.0μF) connected to 12.0 V battery. When switch S is closed so as to connect uncharged capacitor4 (C4=6.0μF), a) how much charge passes through point P from the battery and b) how much charge shows up on capacitor4? q = CΔV http://www.wisheyebio.com/uploads/figure.jpg [Broken] I would like to know the concept of this problem. Would you please suggest me the direction to calculate this problem? P.S. The answer from textbook: a) 7.2μC and b) 18.0μC. I'm trying to find out the solution. Thank you.
