The capacity of a parallel plate capacitor increases with the

As shown in the figure below, if a capacitor $C$ is charged by connecting it with resistance $R,$ then energy given by the battery will be

Four capacitors are connected as shown in the figure below. The equivalent capacitance between the points $P$and $Q$ is

In the following circuit the resultant capacitance between $A$ and $B$ is $1\mu F$.  Then the value of $C$ is
