A spherical capacitor consists of two concentric spherical conductors. Find the capacitance of the spherical capacitor if the outer radius is $2R$ and the inner radius is $R.$

Consider a spherical drop of mercury of radius $R$ with capacitance $C=4\pi \epsilon R.$ If two such droplets combine to form a larger one, what would be its capacitance in terms of $C$ ?

In the circuit given below, the capacitor $C$ is charged by closing the switch $S_1$ and opening the switch $S_2$. After charging, the switch $S_1$ is opened and $S_2$ is closed, then the maximum current in the circuit

Two capacitors, $C_1=2\mathrm{mF}$ and $C_2=8\mathrm{mF}$ are connected in series across a $300 \mathrm{V}$ source. Then

Find the equivalent capacitance between point $A \& B$.

A capacitor of capacitance $4 \mu \mathrm{F}$ is charged to a potential difference of $6 \mathrm{V}$ with a battery. The battery is then removed and in its place another capacitor of capacitance $8 \mu \mathrm{F}$ is introduced and the circuit is closed. The potential difference attained by each of the capacitors in $\mathrm{V}$ is

A circuit is shown in the following figure for which $C_1=(3\pm 0.011)\mu \mathrm{F}, C_2=(5\pm 0.01)\mu \mathrm{F}$ and $C_3=(1\pm 0.01)\mu \mathrm{F}.$ If $C$ is the equivalent capacitance across $AB,$ then $C$ is given by
