Three equal capacitors,each with capacitance $C$,are connected as shown in the figure. The equivalent capacitance between $A$ and $B$ is:

The equivalent capacitance between $A$ and $B$ in the given circuit is (in $\mu F$)

Three capacitors are connected to a $D.C.$ source of $100 \; V$ as shown in the figure. If the charges accumulated on plates $a, b, c, d, e,$ and $f$ are ${q_a}, {q_b}, {q_c}, {q_d}, {q_e},$ and ${q_f}$ respectively,then:

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 $\mu F$)
