If the equivalent capacitance between points $A$ and $B$ of the combination of capacitors shown in the figure is $6C$, then the capacitor $C^1$ is: (in $C$)

Consider the combination of $2$ capacitors $C_{1}$ and $C_{2}$,with $C_{2} > C_{1}$. When connected in parallel,the equivalent capacitance is $\frac{15}{4}$ times the equivalent capacitance of the same capacitors connected in series. Calculate the ratio of the capacitors,$\frac{C_{2}}{C_{1}}$.

Two capacitors having capacitances $8 \mu F$ and $16 \mu F$ have breaking voltages $20 \ V$ and $80 \ V$ respectively. They are connected in series. What is the maximum charge they can store in this combination in $\mu C$?

Find the equivalent capacitance between $A$ and $B$.
