The potential at the point $B$ in the given figure is . . . . . . $V$.

“The magnitude of effective capacitance in series connection of capacitors increases.” Is this statement true or false?

$A$ 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

Ten capacitors are joined in parallel and charged with a battery up to a potential $V$. They are then disconnected from the battery and joined again in series. The potential of this combination will be ....... $V$.

Four capacitors,each of capacitance $16 \mu F$,are connected as shown in the figure. The equivalent capacitance between points $A$ and $B$ is: . . . . . . (in $\mu F$).

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