Initially, the switch in the figure is in position A for a long period of time, and the voltage of the battery AV is given. (a) What is the initial charges and voltages on capacitors C1, C2 and C3? Now the switch is flipped to position B. (b) Before equilibrium is reached, Capacitor C, is neither in series nor in parallel with C2 and C3. Why is that? (c) How are C2 and C3 connected? What is the equivalent capacitance of C2 and C3 (C2,3)? (d) Positive charge flows from C, to C2, which also induces charge on C3. When equilibrium is reached what is the charge and voltage on capacitor C,? Hint: Consider the conservation of charge. (e) What is the charge and voltage on capacitor C2? (f) What is the charge and voltage on capacitor C3? (g) What is the total energy stored in the capacitors when the switch is in position A and when the switch is flipped to the position B? Are they equal? Switch A В + C2 AV
