$27$ identical drops are charged at $22 \ V$ each. They combine to form a bigger drop. The potential of the bigger drop will be............ $V$.

Five capacitors of capacitances $C_1 = C_2 = C_3 = C_4 = 10 \mu F$ and $C_5 = 2.5 \mu F$ are connected in a bridge configuration, where $C_1$ and $C_2$ are in one arm, $C_4$ and $C_3$ are in the other, and $C_5$ is the central capacitor. The combination is connected to a $50 \ V$ battery. Find the equivalent capacitance of the network and the charge on each capacitor.

An electrician requires a capacitance of $6 \mu F$ in a circuit across a potential difference of $1.5 kV$. $A$ large number of $2 \mu F$ capacitors which can withstand a potential difference of not more than $500 V$ are available. The minimum number of capacitors required for the purpose is

For the circuit shown in the figure,the charge on the $4 \mu F$ capacitor is $....... \mu C$.

$A$ circuit is shown in the figure for which $C_1=(3 \pm 0.011) \mu F$,$C_2=(5 \pm 0.01) \mu F$,and $C_3=(1 \pm 0.01) \mu F$. If $C$ is the equivalent capacitance across $AB$,then $C$ is given by:

In the following diagram,the charge and potential difference across the $8\,\mu F$ capacitor will be nearly:
