We need to connect a capacitor of $16\ \mu F, 1000\ V$. However,we only have capacitors of $8\ \mu F, 250\ V$ available. How many such capacitors are required?

The effective capacitance between points $A$ and $B$ shown in the circuit is

Five capacitors,each of capacity $C$,are connected as shown in the figure. The resultant capacity between $A$ and $B$ is $14 \mu F$. The capacity of each capacitor is (in $\mu F$)

In the adjoining figure,the potential difference between $X$ and $Y$ is $60 \ V$. The potential difference between the points $M$ and $N$ will be: (in $V$)

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....$V$

In the circuit shown,find $C$ if the effective capacitance of the whole circuit is to be $0.5\,\mu F.$ All values in the circuit are in $\mu F.$
