Three capacitors, each of capacitance $120\mu \mathrm{F}$, are connected together in series. This network is then connected to a $10\mathrm{kV}$ Supply.

Calculate the total energy stored.

A $20\mu \mathrm{F}$ Capacitor is charged up to $200 \mathrm{V}$ And then disconnected from the supply. It is then connected across a $5.0\mu \mathrm{F}$ Capacitor.

Calculate the combined capacitance of the two capacitors in $\mu \mathrm{F}$.

A $20\mu \mathrm{F}$ Capacitor is charged up to $200 \mathrm{V}$ And then disconnected from the supply. It is then connected across a $5.0\mu \mathrm{F}$ Capacitor.

Calculate the charge they store.
