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 ....... $V$.

Two capacitors $A$ and $B$ with capacitances $2 \mu F$ and $3 \mu F$ respectively are connected in series with a $10 \ V$ battery as shown in the figure. When the switch $S$ is closed and the two capacitors get charged fully,then:

$A$ circuit has a section $AB$ as shown in the figure. If the potential difference between points $A$ and $B$ is $V$ volts,then the potential difference across $C_1$ is

Three capacitors of $2\,\mu F$,$3\,\mu F$,and $6\,\mu F$ are joined in series,and the combination is charged by means of a $24\,V$ battery. The potential difference across the plates of the $6\,\mu F$ capacitor is.......$V$.

Four capacitors with capacitances $C_1 = 1 \, \mu F$,$C_2 = 1.5 \, \mu F$,$C_3 = 2.5 \, \mu F$,and $C_4 = 0.5 \, \mu F$ are connected as shown and are connected to a $30 \, V$ source. The potential difference between points $B$ and $A$ is....$V$

Three condensers of capacities $C_1$,$C_2$,and $C_3$ are connected in series with a source of e.m.f. $V$. The potentials across the three condensers are in the ratio:
