Two capacitors of $1\,\mu F$ and $2\,\mu F$ are connected in series. The resultant capacitance will be ..... $\mu F$.

“The magnitude of effective capacitance in series connection of capacitors increases.” Is this statement true or false?

Two capacitors connected in parallel having the capacities $C_1$ and $C_2$ are given $q$ charge,which is distributed among them. The ratio of the charge on $C_1$ and $C_2$ will be

The effective capacitance between the points $P$ and $Q$ of the arrangement shown in the figure is......$\mu F$

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 $\mu F.$

Two capacitors of capacities $2 \mu F$ and $4 \mu F$ are connected in parallel. $A$ third capacitor of $6 \mu F$ capacity is connected in series with this combination. $A$ battery of $12 \text{ V}$ is connected across this combination. The charge on the $2 \mu F$ capacitor is: (in $\mu C$)
