Two equal capacitors are first connected in series and then in parallel. The ratio of the equivalent capacities in the two cases will be

Three capacitors,each of capacitance $C$ and breakdown voltage $V$,are connected in series. Find the equivalent capacitance and the equivalent breakdown voltage.

When a series combination of $2.0\ \mu F$ and $8.0\ \mu F$ capacitors is connected to a $300\ V$ potential difference,the charge on the $2.0\ \mu F$ capacitor is .....

Figure $(a)$ shows two capacitors connected in series and joined to a battery. The graph in figure $(b)$ shows the variation in potential as one moves from left to right on the branch containing the capacitors. If the graph represents the potential across the capacitors,then:

All six capacitors shown are identical. Each can withstand a maximum of $200\, V$ between its terminals. The maximum voltage that can be safely applied between $A$ and $B$ is.....$V$

Three capacitors of $2.0\;\mu F$,$3.0\;\mu F$,and $6.0\;\mu F$ are connected in series to a $10\,V$ source. The charge on the $3.0\;\mu F$ capacitor is ........ $\mu C$.
