Find the effective capacitance between points $P$ and $Q$ in the circuit shown in the figure in $\mu F$.

Find the equivalent capacitance across $AB$ in $\mu F$ (all capacitances are in $\mu F$).

$A$ metallic sheet is inserted between the plates of a parallel plate capacitor. The capacitance of the capacitor

In the given circuit,if the potential difference between $A$ and $B$ is $80 \ V$,then the equivalent capacitance between $A$ and $B$,and the charge on $10 \ \mu F$ capacitor respectively,are

In the circuit shown in the figure,the total charge is $750\, \mu C$ and the voltage across capacitor $C_{2}$ is $20\, V$. If $C_{3} = 8\, \mu F$,then the charge on capacitor $C_{2}$ is $....\mu C$.

The charge on each capacitor when a voltage source of $15 \ V$ is connected in the circuit as shown,is (in $\mu C$)
