Find the equivalent capacitance between two points $A$ and $B$ for the given circuit. (Capacitance of each capacitor is $C = 3 \mu F$.) (in $\mu F$)

In the given circuit,each capacitor has a capacitance of $3\,\mu F$. What is the equivalent capacitance between points $A$ and $B$ in $\mu F$?

$A$ capacitor is made of a flat plate of area $A$ and the second plate has a staircase-like structure. The width of each stair is $a$ and its height is $b$. The total width of the plate is $2a$. The distance between the flat plate and the first part of the staircase is $d$. Find the capacity of the capacitor.

In the circuit shown in the figure,the effective capacitance between $A$ and $B$ is ...... $\mu F$.

In the given capacitor network,$C_1 = 10\,\mu F$,$C_2 = 5\,\mu F$,and $C_3 = 4\,\mu F$. What is the resultant capacitance between $A$ and $B$ in $\mu F$?

Assertion : If three capacitors of capacitances $C_1 < C_2 < C_3$ are connected in parallel,then their equivalent capacitance $C_P > C_S$,where $C_S$ is the equivalent capacitance in series.
Reason : $\frac{1}{C_P} = \frac{1}{C_1} + \frac{1}{C_2} + \frac{1}{C_3}$
