Three capacitors of capacitis `4muF, 8muF and 12muF` connected in series. If the charge on the `8muF` capacitor is `1201muC` then find the charge on each capacitor.

Two capacitors of capacities 2muF each are connected in series. The effective capacitance in muF is

Three capacitors each of capacitance 1muF are connected in parallel. The resultant capacitance of the combination is

Three capacitors of capacities 2muF, 4muF and 8muF are joined in series and the combination is connected to a 12V source. Calculate the energy stored in the combination when these are fully charged.
