Example: Find q and V on All  Capacitors C is charged in position A, then S is  thrown to B position Initial voltage across C 1 : V = 12 Initial charge on C 1 : q 10  = 12 x 4 = 48 μ C After switch is thrown to B: Charge flows from C to C and C 3 V = V 23  (parallel branches) q and q in series: q = q = q (C = 2 μ F)
