33. In an electric circuit two capacitors C1 and C2 are once connected in parallel, once in series. With the parallel connection one measures a total capacity of 8μF, with the series connection a total capacity of 1.5μF. a) What are the capacitances of the capacitors C1 and C2? b) The larger capacitance C1 is now charged to 100V and disconnected from the voltage source. What voltage is measured when capacitor C2 is then switched in parallel to C1? How big is the field energy before and after connecting the capacitors?
