When a series combination of $2.0\ \mu F$ and $8.0\ \mu F$ capacitors is connected to a $300\ V$ potential difference,the charge on the $2.0\ \mu F$ capacitor is .....

$A$ capacitance of $2\ \mu F$ is required in an electrical circuit across a potential difference of $1.0\ kV$. $A$ large number of $1\ \mu F$ capacitors are available which can withstand a potential difference of not more than $300\ V$. The minimum number of capacitors required to achieve this is

Find the equivalent capacitance between $A$ and $B$. (in $C$)

The equivalent capacitance between $A$ and $B$ is......$\mu F$.

Four identical rectangular plates with length,$l = 2 \, cm$ and breadth,$b = \frac{3}{2} \, cm$ are arranged as shown in the figure. The equivalent capacitance between $A$ and $C$ is $\frac{x \varepsilon_{0}}{d}$. The value of $x$ is (Round off to the Nearest Integer).

Three capacitors of capacitance $3\,\mu F$ are connected in a circuit. Then their maximum and minimum capacitances will be
