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 of capacitance $3\,\mu F$ are connected in a circuit. Then their maximum and minimum capacitances will be

When three capacitors of equal capacities are connected in parallel and one of the same capacity is connected in series with the combination,the resultant capacity is $4.5 \mu F$. The capacity of each capacitor is: (in $\mu F$)

Three capacitors $2 \mu F$,$3 \mu F$,and $5 \mu F$ can withstand voltages up to $3 \, V$,$2 \, V$,and $1 \, V$ respectively. Their series combination can withstand a maximum voltage equal to.....$V$.

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

Find the net capacitance between $A$ and $B$.
