Find the equivalent capacitance between $A$ and $B$ of the following arrangement:

The equivalent capacitance between points $A$ and $B$ in the figure shown below is .......... $\mu F$.

In the circuit shown,a potential difference of $60\,V$ is applied across $AB$. The potential difference between the points $M$ and $N$ is.....$V$.

Two capacitors,each having a capacitance of $2 \mu F$,are connected in series. What will be the effective capacitance of these capacitors (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 $\mu C$)

In the given circuit,what is the electric potential at point $C$ in $volts$?
