The difference between the equivalent capacitances of two identical capacitors connected in parallel and in series is $6 \mu F$. The value of the capacitance of each capacitor is (in $\mu F$)

The equivalent capacitance of the combination shown in the figure is:

What is the effective capacitance between $A$ and $B$ in the following figure in $\mu F$?

$A$ series combination of $10$ capacitors,each of value $C_1$,is charged by a source of potential difference $4V$. When another parallel combination of $8$ capacitors,each of value $C_2$,is charged by a source of potential difference $V$,it has the same total energy stored in it as in the first combination. The value of $C_2$ is

Two equal capacitors are first connected in series and then in parallel. The ratio of the equivalent capacities in the two cases will be

Three capacitors $1\,\mu F$,$2\,\mu F$,and $4\,\mu F$ are connected in series to a $10\,V$ source. The charge on the plates of the middle capacitor is:
