Three capacitors of capacitance $C$ ($\mu F$) are connected in parallel, and this combination is connected in series with another capacitor of capacitance $C$. If the effective capacitance is $3.75 \mu F$, then the capacity of each capacitor is: (in $\mu F$)

In the circuit as shown in the figure,the effective capacitance between $A$ and $B$ is ........ $\mu F$.

$A$ number of capacitors,each of capacitance $1\,\mu F$ and each of which gets punctured if a potential difference exceeding $500\,V$ is applied,are provided. An arrangement suitable for giving a capacitance of $2\,\mu F$ across which $3000\,V$ may be applied requires at least:

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:

The equivalent capacitance in the circuit between $A$ and $B$ will be.....$\mu F$.

If the equivalent capacitance between points $A$ and $B$ of the combination of capacitors shown in the figure is $6C$, then the capacitor $C^1$ is: (in $C$)
