Four capacitors of $25\mu F$ each are connected as shown in the figure below. If the D.C. voltmeter read $200 \mathrm{V}$. charge on each plate of the capacitor is ____.

The figure shows a capacitor of capacitance $\mathrm{C}$ connected to a battery via a switch, having a total charge ${\mathrm{Q}}_0$ on it, in steady-state. When the switch $\mathrm{S}$ is turned from position $\mathrm{A}$ to position $\mathrm{B}$, the energy dissipated in the circuit is

Figure shows charge $\left(\mathrm{q}\right)$ versus voltage $\left(\mathrm{V}\right)$ graph for series and parallel combination of two given capacitors. The capacitances are:

A parallel plate capacitor $C$ with plates of unit area and separation $d$ is filled with a liquid of dielectric constant $K=2$, the level of liquid is$\frac{d}{3},$initially. 
Suppose, the liquid level decreases at a constant speed $v$, the time constant as a function of time is

Figure shows a network of capacitors where the number indicates capacitances in micro Farad. The value of capacitance C if the equivalent capacitance between point A and B is to be $1 \mu F$ is :

The equivalent capacitance of the combination of the capacitors is
