In the circuit shown in the figure,$C = 6\,\mu F$. The charge stored in the capacitor of capacity $C$ is......$\mu C$.

Seven capacitors,each of capacitance $2 \mu F$,are to be connected to obtain an equivalent capacitance of $\left(\frac{10}{11}\right) \mu F$. Which of the following combinations is possible?

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 $C$)

The figure shows a network of five capacitors connected to a supply voltage '$V$'. The equivalent capacitance and the energy stored in the network are respectively:

Eight capacitors,each of capacitance $C$,are connected as shown in the figure. The effective capacitance between $A$ and $B$ is

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,$\frac{C_{2}}{C_{1}}$.
