1. The problem statement, all variables and given/known data A capacitor of capacitance 9 μF is fully charged from a 200 V dc supply. The capacitor is now disconnected from the supply and connected in parallel with an uncharged 3 μF capacitor. Once the 3 μF capacitor is fully charged, it is removed and discharged. a) What charge remains on the 9 μF capacitor? b) How many times would this process have to be repeated in order to reduce the charge on the 9 μF capacitor to below 50% of its initial charge? c) What would be the pd between the plates of the 9 μF capacitor now be? 2. Relevant equations Q=CV 3. The attempt at a solution a) I said that the 3μF capacitor will be fully charged when the voltage across both capacitors is the same,let's say Vx. Since energy has to be conserved then Ei=Ef therefore C1V^2 = C1Vx^2 + C2Vx^2 <=> Q1' = 1.5588*10^-3 C . Am i doing this correct ?
