Two capacitances of capacity $C_1$ and $C_2$ are connected in series and a potential difference $V$ is applied across the combination. The potential difference across $C_1$ will be:

Capacitors of capacities $C_1, C_2$ and $C_3$ are connected in series. If the combination is connected to a supply of $V$ volt,then the potential difference across capacitor $C_1$ is

Four metal plates are arranged as shown. Find the equivalent capacitance between $ X $ and $ Y $. ($ A $ = Area of each plate,$ d $ = distance between adjacent plates)

The potential difference across the $4 \mu F$ capacitor in series with the parallel combination in the following circuit is: (in $V$)

$A$ 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

Six identical square metallic plates are arranged as shown in the figure. The length of each plate is $l$. The equivalent capacitance of this arrangement would be . . . . . . .
