A circuit with C1=6*10^-6F, C2+3*10^-6, and potential difference=20V. Capacitor C1 is first charged by closing switch S1, Switch S1 is then opened, and the charged capacitor is connected to the uncharged capacitor by closing S2.
a) calculate the initial charge acquired by C1, after S1 is closed.
b) calculate the final charge on each capacitor
c) calculate the final voltage on each capacitor
