$A$ capacitor of capacitance $C_1 = 1\ \mu F$ can withstand a maximum voltage $V_1 = 6\ kV$ and another capacitor of capacitance $C_2 = 3\ \mu F$ can withstand a maximum voltage $V_2 = 4\ kV$. When the two capacitors are connected in series,the combined system can withstand a maximum voltage of......$kV$.

$A$ 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

What is a parallel connection of capacitors? Obtain the formula for the effective capacitance in the parallel combination of two different capacitors.

Which quantity is same in each capacitor of series connection?

The equivalent capacitance of the combination of capacitors shown in the figure between the points $P$ and $N$ is:

Two parallel plate capacitors are connected in series. Each capacitor has a plate area $A$ and a separation $d$ between the plates. The dielectric constants of the media between their plates are $2$ and $4$. The separation between the plates of a single air capacitor of plate area $A$ which effectively replaces the combination is:
